Frontend PM. Autofill the subject

I am setting up the multivendor shop and I have taken the code from here: https://www.ads-software.com/support/topic/pm-with-author
to fill up the Username automatically, an I have put the button on every good page. Is it possible to take the name of the good and put it in the field of subject?
