Exit Variables in Design Studio

Hi all,

At first i want to say sorry for my english.

I want to ask you about an idea i have, and i think it could be possible to do. If I make a Query in Query Designer, i can create a new Exit Variable which you must to fill with data when you run the Design Studio which contains that query.

I need it, but, i need create a new DATEFIELD and when you put a DATE into it, the exit variable take that DATE.

Is it possible? and how?

Thank you.
