How can I get the RAMP tool to assign a fixed session?

I want to assign a fixed session, such as Session A, for my destination screen in the Destination Screen Details. How can I do this?

You have to select the command handler so that the line it is on goes blue, not just tick the checkbox. Then you associate a session with it.

This may seem unusual, but sometimes multiple command  handlers are associated with a single destination form and therefore you have to actually indicate which one you want to change the session for.
