MarketPress Adon

So im really confused how the Add Variation option doesn't allow the variation to be a downloadable file
see as how theres a ton of products that are now digital, like books.. which is something im trying to do here, but i cant because i want to sell a physical book and a digital copy..

is this ever going to be added on, id appreciate hearing what the future looks like for marketpress because ill have to find something else, but i dont want to cause i like wpmudev! :-p
Would also be nice to sell access to a page, i know this can be done with the Membership plugin but then that kind of messes up the structure of things...
