Group by date / days

It seems that this is an easy question... but I couldn't find the way...
I want to be able to group by date but (day by day).
Filter all *.ppt? files (powerpoint)
group by date but I want grouped all power point files per day... not like "last year", "long time ago" that seems to be the default way.
Thanks !

Custom grouping can be done via a script (example here that lets you custom-group by size). That's the only way at present.

Hi all! o) I'll try to add day-by-day grouping to the grouping-column-set, I'm in progress rebuilding these, but that can still take some more days to finish.

Ok, thanks... if it is customizable would be even better like by weeks or months ... as it would help to organize docs as being produced or sent/received
