I mean I totally see the use case buuut it's a bit tricky to implement so idk if it's worth it

Not wanting to flog this too far but something akin to the CRON interface would cover everything.

Perhaps that's not impossible to implement? I do understand that whatever code is used has to run in the core of Hive and be extremely performant.

Anyway I don't see a lot of usage of recurrent transfers yet so we should keep an eye on this if my use case starts to get traction.
