T2 page sync for epubs not bought from sony store

I have a t2 and an android phone and I read on both of them at different times... the page sync feature works GREAT if its a book bought from the store, but it doesnt seem to work at all with epubs loaded via calibre.

Is there a way to make page sync work between the sony reader software on android and the T2 for non-drm sideloaded Epubs?
