Ability to Freeze columns in a Group

[kzsnow]

As a user, I want to be able to right-click and 'Freeze' a column contained in a group so that I can benefit from the added organization of grouping without losing the convenience of popping a couple columns onto the front quickly and easily. In v20, one could do this and it would 'split' the group. In v21, 'Freeze' is grayed out for columns in a group. If splitting the group is an issue, IMO it would make more sense probably to allow freezing grouped columns, but just free them from their group if 'Freeze' is selected from the right-click menu.
