Does anybody know of a way to "trick" design tables intochanging a parameter that is established in equations?

i.e. in equations, I create a variable or parameter called "length"and set it to a value.

In design tables, the values that change are usually a dimension(i.e. name@sketchnumber). I don't have that identifier with theparameter.

Is there a way to make it work in a design table?

Pro E can do it....I know SolidWorks won't let me down.....

Thanks!
