variables as offsets for ref planes

Hi guys

This sounds easy, but I haven't been able to do it. I would like to define a plane whose offset is a named variable.

In the plane reference dialog window, it only accepts numerical values and won't let me type a variable name.

My other alternative, is to make the plane offset dimension visible, and then by right clicking on the dimension,

I could set it to a linked variable. But I have not been able to show the plane offset dimension. What should I do?
