Rubric grade conversion

Have just stumbled across the rubric creator in the testflight version of the app - what i've been waiting for!

Is there any way to convert the score it generates into a grade?? ie 2/16 = 1-, 4/16 = 1=, 6/6 = 1+.... ??

TIA

Hi,
You can't make that conversion in the same cell but you only have to Add column > Calculation > Average > Select your grade in 'Grade type' and in that average configuration tap on the rubric's header.
Here a couple of screenshots
