Wouldn't it be really great if there was a right click option when selecting a category to include in a package, whereby you could specify a date so that items modified since that date are selected for you. Tedious at the moment have to reference the output of a SQL query identifying all those objects from a spreadsheet.

Even better to then capture that information as part of the package file and provide another option in the MMC, besides Edit, whereby I can select the package and choose Refresh, which will use the same date to update the package, without me having to create another one from scratch and working through the a new list of modified objects.
