Focus & Filter CMS Collection Items w. State Change

I think I might have a bit of a challenge. Is there a way for a user to filter & focus items in a CMS collection which is then reflected in a state change of equal collection items?

I’m trying to make a sheet music library where users can select a piece of music and then filter the goals of the piece they selected. They must only be able to filter for one piece at a time & 1 goal at a time with the focused goal/ piece reflected in sister CMS lists.

Here is my public share link:

< go to ‘Library’ >

This shows the user flow for a single piece of music. I still need to…
[1] add filter items for multiple pieces
[2] organize the CMS so that adding a piece object creates the library display & the goal sections
