When selecting different objects the values in Transform / Move updates to reflect the values of the currently selected object, but not in Scale.

My scenario is to change each objects size by adding/subtracting values. ex. add 0.5 inch, subtract 1 inch, so the unit used and not %.

Is there a way to make it update also? Since there is already an "Apply to each object separately", it is possible to reset the values for the newly selected object instead.

I tried the "Clear" button but it reverts the unit to "%". I want the unit to be maintained as, say "inch" or "mm".

Is it possible to use "Clear" but maintain the unit?

I don't think so.
