Rubrics : how to add half points

Hello,

I'm just discovering the rubric grading and think that's a great feature (and I just take the advantage of this post to ask where I could send my enthousiasm about uploading feedback files as a zip file ?).

But when I define 1,5 or 2,5 as a grade for some criteria, they get converted... Is there a way to  put some rubric like this:

Criteria 1 : /2 pts

Criteria 2 : /1,5 pts

Criteria 3 : /3,5 pts

Criteria 4 : /2,5 pts

Criteria 5 : /0,5 pts

______________

Total :     /10

Another question by the way: there is no way lo leave each point description empty (to leave it to the evaluator to make those comments individually), is there ?

Thank you for your help !
