Offline Sync

Often I go away for long periods of time and sync a huge amount of comics to read while I’m away to my iPad.
I’d like to be able to delete read comics to free up space for other items while I’m away and when I go home and sync my iPad and YAC Library on my PC and the comics I’ve read update on my YAC Library.
Currently this isn’t an option I believe. For it to do that I have to sync with YAC Library before I delete. Can this option be looked at?

Right now when you delete a comic you also delete it’s metadata, I’ll try to think about a solution.
