Grouping Custom Dateteime Columns

the standard datetime columns (eg. Modified, Created) are grouped "smart" with groups like Today, Yesterday etc.
the new custom columns of dopus are strictly grouped by theire value, is this a bug or a feature?

It would be nice if the grouping logic of the standard datetime columns could be used and overwritten with the "noautogrouping" parameter.

A fix for this should be in the next update, assuming no problems are found at the last minute.
