The protocol can do this with NIP-51 and the “a” tag but it’s not easy to implement so the question is whether users want it or not. No reason for devs to build something that users don’t want.

Which means if you and others want to see it, devs gonna have to hear you ask for it. And I hope you do. Very loudly!
Right now this feature (a-tag support for NIP-51 lists) is not implemented anywhere in the wild with the exception of my own rickety personal playground nostr desktop client. I’d love to see that change! 🙏🏼
