if possible, I want to set an attributes(product type) into Marketo Program, but there is no way to do it,,, am I correct?
That would be way better than using naming in my opinion. And yes, an attribute of a program would be a Program Tag:
But you can't use these tags in Smart Campaign filters. Seems Marketo envisioned them to be for reporting only. I believe there are ideas here to expand the use of Program Tags, but so far Marketo hasn't listened.
EDIT: I knew Greg had this on his list: https://nation.marketo.com/t5/ideas/have-tag-and-channel-constraints-to-quot-program-status-is/idi-p/263646
