Moving from IL-2 Launcher to Steam?

[[=PzG=]-Southernbear]

I don't really know where else to put this question frankly...

 

I know this is an odd question but we all know about if you bought the game on steam here is the A,B and C possess to link your steam account to IL-2 to buy IL-2 products off the website

 

However is there a way to go backwards? disregard the reason...I suppose I could say a standardization of games so a friend has all his games on steam but is there a way to use the fact he has a IL-2 account and the game with launcher and get the game on his steam account without needing to buy at least BoS on steam all over again and log into his IL-2 account from there.

 

TL:DR is there a way of letting steam know you already own BoS and make steam download it through Steam for free or do you have to by BoS through steam to do this?

No, you need to buy BOS in Steam for that. You can create a shortcut to non-steam games in your library but that's about it. The game would not be updated using the steam updates.
