[ARCHIVED] Custom Groups for Calculated Metrics and Attributes

I have dozens of calculated metrics and attributes.  It would be nice to be able to group and sort these in a way that makes managing them easier?  For example, all of my calculated metrics are visible when I click Add then expand the group "Calculated Metrics".  If I could have my own groupings to organize my calculated metrics and attributes better as opposed to having them all in one large grouping; then I could arrange them in a meaningful way.
