Populate dropdown list with Sonos favorites?

Still pretty new to HA and have figured out most of what I’ve needed thus far. One thing I’d like to do is have a dropdown menu on my dash from which to choose a Sonos playlist. I’m currently using the Sonos card and have that set up and working fine, but my workflow would essentially be me hitting a button to choose a speaker group, then a popup letting me choose a specific favorite from a list.

I’m somewhat familiar with creating general drop downs, but I’m not sure if it’s even possible to have it populate with my Sonos favorites. Any help is appreciated!
