@John Gelona Not in ReportCaster but what about using EDAMAIL might help you in the short-term, I would definitely log a NFR so this functionality can be included in ReportCaster.
See developing reporting applications manual for syntax:
EX EDAMAIL to=addresslist, [toaddr= {addresslist|%[app/]addresslist.fex}, ] [cc=cadrlist1,] [ccaddr=cadrlist2,] [bccaddr=bcadrlist,] [from=address,] [fromaddr=address,] [replyto=address,] [importance=low|normal|high,] [subject=string,] [flags=value,] [filetype=extension,] [filename=file,] [message=body message]
