How to sort folders into folders in Stored sessions screen?

Hello.
I have WinSCP 4.3.7
I want to reorder the folders in "Stored sessions" screen, move a folder inside another, in the same manner than you move a session entry from a folder to another: drap and drop. Is it posible?
Thanks.

No, dragging session folders is not supported.
You have to create new target folder and drag all sessions individually.
