Our customer has multiple evaluation questions on a legacy form and we are moving them to QM. It seems as if the QM system will only allow a single type of evaluation question on a form; 1-5 or Y/N.
Unfortunately the answer to all your questions are no, no and no
The following can be done in v8.0 which might address some of the issues
a) ability to use both Y/N and 0-5 in the same evaluation form
b) ability to use different evaluation forms for a particular call
c) each section is not limited to 10 questions but the entire form is limited to 100 questions (my condolences to the evaluator)
