Allow parent groups to contain student emails/Allow robomailer to contain created parent groups

Currently in DSP, the parents of a competition team, for example, can be placed in a group for easy contact. Through the parents tab, we can select all the parents in that group and email them. However, for our older teams, we would also like the dancers to be able to be included on this list as the information pertains to them. I realize that in the Robomailer, we are able to email individual classes and it is an option to email students and parents at the same time with this function, but again, that leaves us sending multiple emails for each of the classes that are included within our competitive teams instead of being able to send one mass email. It would be great if you could include the groups we have set up in the Robomailer options list, or create functionality where we can check a box and select to send the parent emails to their students as well. Thank you!
