Samsung Freeform / Link R350 / R351 / R355

I am looking for a way to add a contact into more than one group...and I can't find anything online, in the manual, etc.

Surely I am not the first person that has attempted to add a contact into more than one group on the r351?

This would be a deal-breaker for me if this phone doesn't have that capability.

Thanks all!!!

Alltel has just released the new open face qwerty but they don't have any info i called the local corporate store and they told me the phone didn't exist. The store I work at has them in stock, but I look online and every page that tells you anything about the phone tells you that there is a $50 MIR on it but not one site has a link to it or a URL of it anyone out there happen to find it please let me know.
