address book--how do you make a group entry?

[ursusaureus]

I can't seem to make a group entry in my address book.  Each entry seems to be limited to a single name.  So if under IdiotCommittee as a 'name' you put idiot-1@stupid.edu,idiot-2@stupid.edu, etc., the panel says it is not a valid address.  How can I made an address that will send to a group of names?  I hope this can be done without code, which is currently beyond me... Thanks!

Roundcube does not yet support groups in the addressbook. This is planned for a later version.
