Collecting Form - Resource Template assign & Multiple values?

The current release for the module doesn’t seem to include a function to assign a Resource Template to a form, or allow for multiple values to be selected. When searching, I found that an old beta version included these features but I couldn’t get them implemented (I presume the version it was made for is simply too old now).
(Found through this question: Collecting Form - assigned item set not applying assigned resource template to newly added items - #2 by Daniel_KM)

Is there any way now to assign a resource template to a form?
And to add in the function to select multiple values for a field?
Would this be possible?
