You should consider using special WR load testing functions available for
GUI VUsers only, such as start_transaction, end_transaction, rendezvous etc.
(see WR Help for complete reference). You needn't create loops in WR scripts
to perform some actions repeatedly. You can set desired number of iterations
in LR Controller and you can create different groups of GUI VUsers there as
Please note that you can only run 1 GUI VUser per load generator unless you
use Terminal Server.

Hope that helps.
