Is there any reason you couldn't just add a flag?

IMAP-wise it's:

label STORE message-id +FLAGS (FlagName)

and

label FETCH message-id FLAGS


e.g. [trimmed a little]

* OK Dovecot ready.
A LOGIN user pass
A OK Logged in.
B SELECT INBOX
* FLAGS (\Answered \Seen [.etc.])
* OK [PERMANENTFLAGS (\Answered \Seen ... \*)] Flags permitted.
* 30129 EXISTS
* 0 RECENT
* OK [UNSEEN 408] First unseen.
* OK [UIDVALIDITY 1202523566] UIDs valid
* OK [UIDNEXT 153176] Predicted next UID
B OK [READ-WRITE] Select completed.
C FETCH 30029 FLAGS
* 30029 FETCH (FLAGS (\Seen))
C OK Fetch completed.
D STORE 30029 +FLAGS (SeenByProcess)
* FLAGS (\Answered \Seen [.etc.] SeenByProcess)
* OK [PERMANENTFLAGS (\Answered \Seen ... SeenByProcess \*)] Flags permitted.
* 30029 FETCH (FLAGS (\Seen SeenByProcess))
D OK Store completed.
