Make Design Table Output Other New Dimensions

[newreynolds]

I'm trying to determine a change in belt length of a simple 2 pulley, tensioner/idler system as the tensioner travels through it's range of motion. The tensioner and idler are linked with a linkage.

I am trying to use a design table to do this but it seems I can only get the table to output the belt length of the last-rebuilt configuration. Is there a way to get around this?

Thanks.
