3point square update?

Good day.
When creating a 3 point square.
you select the origin enter the width value let say 20mm...click which side width is going to be from the origin.
The next value would be the height.
but since the next value should be the height...and I always start typing the value and mess things up.

What I am trying to say in this situation for not needing to press tab for the next value....since the next value is the height anyways.
This will speed thing up.

tnx!
