doveadm sync subscribed folders only

Heya,

is there a simple way to use "doveadm sync" for subscribed folders only?

Since the migration from UW-IMAP, our users can actually subscribe to non-mbox files and now, when we are pushing new servers out, we are migrating our mboxes to dbox format and we would like to migrate only subscribed folders.

I know, there is a -m switch which can be used to transfer subscribed folders for each user, but it makes it quite unusable with escaping and all other problems with such volume, so just wondering if there is a simple way to migrate subscribed folders only.

Thank you in advance,

cheers, Jernej
