Posting “Personas” for grouping (possibly overlapping) sets of accounts

Support pre-defined groupings for platforms where you have multiple accounts. I maintain three broad “personas” with my accounts:

• A “general”/everything persona, including one of my Bluesky accounts and my Twitter and Mastodon accounts, which gets basically everything from me.

• A “professional” persona, which includes all of the above but also LinkedIn.

• A “music” persona, which uses a different Bluesky account, my Twitter account, and Threads, Instagram, and Facebook accounts.

These are all posted as me, not as different brands, but I use them in different ways for different purposes at different times.

Notice these overlap! What I would like to be able to do is set up a profile or grouping—what I am calling a “persona”—like “Default”, “Software”, and “Music”, and have the post automatically shared to that set of accounts, rather than having to select them manually every time.

This is not the same as the existing Teams mechanic—in fact, it’s almost the inverse of it. Instead of having a team managing a shared set of accounts, I have a single person (me!) managing distinct sets of accounts.
