As far as I know it's not possible to stamps strings.
stamps is just for DOPs stuff.

Whenever I tried to stamp strings from the template points I had to stamp
the point number and then do a point() lookup from the copied objects.
Kinda slow but it worked.

Would be interested in other methods too.
