Flie / close = ask before loading unactive session

Hi,

Sometime i open a session just to grab a region or group of regions or export selected tracks i need for another project without activating the session. but often i forget it’s there behind and i go on working on the active session.
After a time i close my session but i don’t want to quit nuendo, and now nuendo automatically activates that session i don’t need… and will take ages to load.
i can terminate nuendo process… but then need to restart it.
would be convinient if a session is unactive that asked if we want to activate it when closing the active region or just close it.
Also if several sessions unactive, wich one to activate.
