How to dimension inside pocket of shell?

[Brad82]

I am using Wildfire 2.0. I have a model where I did a shell feature. The model has one step on the back and the shell follows this step also. This model has a family table where the length of the step changes. I made my detail drawing and inserted a table where I inserted the values from the family table. This worked fine. My problem is that I need to also have a variable dimension on the open side of the shell that dictates the length of the opening. Since I have a shell, it is driven by the wall thickness dimensions. How can I make the opening length vary with the step length and have it in my table without using a dumb table?

Either assign a parameter value with a relation or create an indicator, i.e. sketch ref dim, datum evaluate, annotation feature, etc., and feed it into the table?
