Add/Delete Column Split

hello.

I am using MuseScore 3.0.

After upgrading to 4.0 this time, I can't find 'Add/Delete Column Split'.

You can arrange the bars by simply using the enter key, but after making all the scores as before

Depending on the need, the whole is 3 measures, 2 measures, or a certain section is 5 measures.

There is no way to change it.

Is there any other way to solve this? Or, in 4.0, whole bars into constant bars.

Is sorting missing?

I uploaded a sample video.

I hope you have a nice day and thank you for your reply.
