is there a way to disable auto beam by default and enable it at will?

Yes of course you can disable auto beaming after the fact, but why if you do not need to beam to start with. What good it is to disable auto beam after the fact, since it messes up by adding rests just to keep up the measure fully populated all the time. Now as a programmer if you want everything correctly timed you add a button that checks for score errors to make sure the timing is overall correct when needed. Auto beam does not know what you are trying to do, so this feature should not be a default behaviour of the program as it does not save you time, it actually slows you down. Further more even when I pick a quarter note in a 4/4 measure bar and while entering 4 quarter notes trying to fill the measure with the mouse the program keep adjusting things by replacing unnecessary rests and 16th and eight notes and more rests at will while I enter the notes. So10 second job takes forever and everything is still all messed up. Plus, automatically beams them depending how close notes are from each other, everything is out of control. Now who is going back and double click on EACH bar on a 60 bar Divine Liturgy and fix the mess by selecting beam properties to unbeam them and that’s not all. You need to go back on each note and select note properties to revert back to whatever you wanted because it was automatically altered, unbeaming do not fix the math automatically on the timing and do not put back the notes you originally intended to put in that measure. To clean the mess takes forever. You can not even remove the rests easly without dropping a note with the right duration on them. You always end up having more rests then the actual duration of the notes you need to put on that bar almost each time you populate a bar from the mouse or keyboard.
Either I am doing something totally wrong or the program is conceptually flawed.
If anyone of you could advice the correct way to use the note entry at the least, please respond.
The main issue I have is that what if there is no fixed time signature on the piece you are working. Am I supposed to count each note in the given bar on my manuscript and create a time signature for each bar just to accommodate the program so that the timing of all notes finally falls on the right spot without the automatically added stupid rests I don't need? Why I need to go back spend hours to fix something I did not even intend to score?
Man it is too much!
The program was supposed to make our life practical not the other way around.
Unfortunately many programs I evaluated function this way and one wonders why this issue never comes up and no one complains about.
If anyone knows a program with relaxed note entry rule and checks afterward, I am ready to spend the money.
Please advice.
Thanks.
