One association class for two associations in Visual Paradigm - how?

I would like to ask if it's possible to connect one association class with two associations between two classes?

association class

Right now association class WypozyczenieSprzetu is connected only with 'Oddaje' association. I would like to connect WypozyczenieSprzetu with both 'Oddaje' i 'Wypozycza' but Visual Paradigm does not let me to do it. Do you know any idea on how to do it?
