Is it somehow possible to integrate merging certian accounts in GOG Galaxy?

So, for example:
-Friend A has a Steam, GOG, and XBox account. Galaxy could recognize this and merge the three accounts on the left side. And show all 3 again once clicked on.
-Alternatively you could allow players to merge account by themselves, only for thier instance, of course

And, if the player is online on even 1 of thier accounts, it should display as "online"
