It seems Serice pack 3 fixed the units issue with elevation. Now is it possible to only have elevations show in the drop down for the active design line?

If there are several designlines with different elevations it is quite a drop down list of the elevations in the current file. Seems like in EST 2015 when you made an existing desiglne the active one, only the elevations associated with it were available in the drop down. Can this be fixed in EST 2016 (maybe next release)? Could there be an option added to the configuration to allow all elevations shown or just allow active designline elevations?
