Populating Schedule based on two Criteria

Hi There - I am working on a master schedule for a camp that will populate two sheets, one that has a full weekly schedule for all groups (this part I've figure out), and the second sheet (or multiple sheets) that will populate the activity schedule. 

Essentially, I have a master schedule and want to be able to pull two smaller data subsets from it, one by group, and the other by activity. 

I'm open to any and all changes to make this accessible, thank you!

Below is the master schedule with data

My group schedule (I can drag and it will fill in columns, so easy there), Any adjustments to master will repopulate 

Art Schedule, for example, that I want to set up to auto fill in, so any adjustment I make in the master schedule will reflect here. 

Thanks in advance for any help!
