Custom Form Select Resets Another

Hello!

I have a section that utilizes CMS Filter, Custom Select, CMS Select, and CMS Nest.

See attached image:

The issue is with the section pictured above. Specifically with clearing/resetting the active filter. Is it possible to have 1 dropdown clear the other? Currently the functionality allows for both filters to be applied to the collection list below. I’d like it so that only 1 can be actively filtering at a time. When selecting one drop down it would clear the other.
