Sorry, guess I wasn't clear enough. What I am thinking should work is
...
<!--# call
"PARENTS[0].manage_addFolder(unique_id,unique_id,0,0,REQUEST)"-->
<!--# call "PARENTS[0].manage_changeProperties(counter=counter+1)"-->
<!--# call
"PARENTS[0].manage_changeProperties(unique_id='MyFolder'+_.str(counter))
"-->
