you could try doing what i did make a quick txt.
say u want five diffrent names make 5 difrent quick txt name them
r1 r2 r3 r4 r5
then make a q.txt named /qname and in the q.txt make the q.txt
/nick (insertname)
#5#(!R1)
#5#(!R2)
#5#(!R3)
#5#(!R4)
#5#(!R5)
ETC
then open a convo and type /qname and then it will work as long as you keep the convo open that u put /qname but when it gets to the end it wont start over
