CE-Modify Solid doesn't retain Parametric Variable?

The modify solid tool has the option to use a variable however once complete it doesn't retain the variable link I hope this is an over site and not WAD.

Outcome...

Please fix this (and any other instance) where a user can pick a variable but the parametric solids forget the variable.  If this cannot be fixed please at very least add a note to the user that it's not going to use said values more than the one time; it's misleading.

Thank you,
