Loader jobs can populate Group assigned attributes

So I've got a SQL loader job that loads courses into Grouper, pretty straight-forward stuff. I need to populate some additional attributes on the generated/loaded groups. Could be anything beyond the standard group fields (name, description and membership). Things like meeting location, and internal sequence number, course begin/end date, etc... Ideally, I'd like those (KNG123, 999122, 01-Aug-2015, 10-Dec-2015), to be assigned on the ACCT101-10 group that was created by the courses SQL loader. This info could be used at a later time by hooks, web services, etc.

My initial though would be to just add an additional field to the existing GROUP_LIST type that uses a query that returns group_name, attribute_name, and attribute_value.
