Please describe your issue in as much detail as possible:

when installing a game from my library ask where to install it to, I know if I go to the store and press playnow it tells me where do i want to install it. SSD or SD card. Will be great if that was the case on the library.

Steps for reproducing this issue:

1. on store play now it works it ask where to install it.
2. on the main library it just installs to your defaut storage.
