vRA New VM Request - Mark input boxes "Description" and "Reason for request" as required

Hello,

is it possible to mark the two text boxes "Description" and "Reason for request" as required in vRA 6.2?

I can add my own text boxes using the property dictionary and set them as required but I didn't find the place where to mark the two default boxes as required so they have to be filled in when submitting a new virtual machine request.

Thanks and Best Regards
