There are other programs called "parametric CAD" that are very focused on this type of work. If this is an important feature for you, i would strongly recommend using one of those programs for this work rather than MoI.

SolidWorks would be a good one to check out, I think they have a way to link a parametric variable to Excel.

The focus on MoI is on making things quick and fluid to draw. It's not focused on this kind of process control that you need.
