ITunes :: How To Merge Multiple Account Purchases Into One

I figure I'm not the only one who is going through this, but I am hoping there is a way to merge my iTunes account purchases into 1 account. When I was single I had my personal account and bought music, tv shows, & movies under that iTunes ID. At the same time my future wife was doing the same. Now that we are married and have multiple devices including an iPhone, iPad, & Apple TV I'm looking for a way to merge each of our "pre-relationship", personal purchases into our family account.

I already made the "family" iTunes account that all of our devices use, allowing all store purchases from here-on-out to be able to be utilized on all devices. iTunes Match has helped in the music department because I downloaded all of our music from all account onto my computer and uploaded them to iTunes Match, thus making one large stock pile of collaborated account music which is able to be heard on any device linked to our iTunes Match account.

The problem I'm running into is that there isn't a similar option for TV shows & Movies. Right now they are downloadable from iCloud but only when logged in under the particular account. I have downloaded them all onto my Mac but I can't transfer them to my devices unless I plug them into the Mac or I "Home Share" to my Apple TV. Is there a way for me to open my Apple TV, iPhone, or iPad under my family account and be able to access purchases from our other accounts.
