[Rubrics] Pick middle value in range

Problem statement:

In SpeedGrader, I can set up a Rubric with ranges. When marking, when I click on a range, by default, SpeedGrader picks the highest value possible for that range. e.g. for the 0-5 range, it picks 5.

Proposed solution:

Can you please allow me to set up the rubric so that when I click on a range, then by default, SpeedGrader picks the middle value for the range?, e.g. for the 0-5 range, it should pick 2.5.
