It is great to be able to add a variable that is a table to the Watch window and have the Generate query functionality. What would be extra nice is to have the ability to somehow see which model table that table variable is reading.

I know I can find out by clicking Generate query and looking at the code, but it would be nice to see without having to do that extra step.

One idea would be to add it to the tool tip when hovering over the Value or Type column for that expression.
