Is it possible to use a regular expression in a ..ReplaceStr function

Messages will contain fields with expressions like "REASON->Blood(1.23)" or "REASON->Bone(4.56)" or "REASON->Muscle Mass(7.89)". The word after the "->" can vary. I would like the outputs to be; "REASON(1.23)" or "REASON(4.56)" or "REASON(7.89)", basically removing "->" and the word or words that follow but leaving the parens and the numeric characters within.

Thanks,

Jonathan Harris
