Expand Categories (21, 22) or break pattern?

I reorganized my old study program stuff, and I used headers for each semester. However, in the case of two semesters, I had more than 9 courses, so I ended up with this:

I added a letter to insert the extra course in the correct position. It’s a clear break from the standard structure. On the other hand, restructuring all semesters (i.e., headers across two categories representing study programs) to a format like AC.S.ID, where S stands for the semester, feels a bit… excessive. What do you think?

Hmmm, no longer a student, but my undergrad is organised in one ID then by year, semester, module number. I’m not actively using it anymore, but sometimes I like to go back and take a look at something and it works well for my brain.
I hope this is helpful or you find another solution that works for you :).

Edit… here is the ID
