Hi a.burgess !
So glad to read that you use Everyday Looper for education purposes

!
I understand the problem you have. Doing that for dozens of childs would indeed be time-consuming. I didn't update Everyday Looper recently because I'm working on other projects, but I would like to go back to it soon. So I'll definitely think about something to solve this problem then. However don't expect a new version too soon because there is quite a few new features I would like to add.
In the mean time, your pupils can maybe save their loop, merge all in one track, download the track and load the un-merged track back.
Maybe you could even beta-test the next version of the app so you can tell me before hand if it solves your problem ?
Have a nice day !!
