Seeking best practices for scoring multiple examples (of harmony or rhythm)

Tim Patton, here, from Houston TX. I'm a new member to MuseScore and a self-taught ear-trained drummer looking for wisdom. I want to enter example of musical phrases from literature: e.g. an example from one of any number of music theory texts, e.g. Schoenberg, Fux, etc.

I find the audio playback feature especially helpful because I can't look at music notation and hear it in my head as many trained musicians can. I also would like to avoid having 200 tiny files each containing a measure or a few measures. In my preconceived and ignorant ideal view, I would like to create one score per textbook and separate each example with identifying text, such as "fig 1. p. 27," or some such. But that might be a bad idea for any number of reasons I cannot yet foresee.

If you've used MuseScore in a similar fashion, or if you are just experienced enough with the various palettes and overall eccentricities of the software that you could suggest some ideas, then please kindly share with me what has worked for you. Also, please don't hesitate to sound patronizing; I'm still learning the features and don't mind being spoken down to like I was some kind of idiot novice. I am some kind of idiot novice, after all.

Thank you!
