Dynamic Dates as criteria in smart playlists

[wback]

How can I create a Smart Playlist with an "age" criteria , e.g. [Added].[Age Less] 7 (i.e. added in the last seven days)? That should evaluate to something like [Added] >= Today() - 7, i.e. all items where the [Added Date] is newer than / is equal to Today's Date minus 7. Where the evaluation of "Today's Date" has to be done during real time, i.e. not when the criterium is set, but when the user watches the playlist.
Currently, I have to go every morning through my play lists and change the date manually (e.g. [Added] > 12/10/2021) - not something very user friendly.

It is not possible to create a playlist that references the current date. You can only sort by date added to see the most recently added files.
