Is it possible to have dropdowns within actions pull from lists?

I'm using actions within a project maintenance dashboard for my team. An issue I'm having is whenever a team member leaves/a new person joins the team, I'm having to go in and manually update the dropdown used to assign a project to a person on the team. I was wondering if there was a way to dynamically update the dropdowns within actions and, if not, if that can be added in the future as I feel like it would be very useful. I'm using metabase version 0.49.1.
