I'll do it a "bit" different.
Currently the Filter Wizard uses all stored pictures as source for it's database query.
In future you can define a picture set the Filter Wizard works with.

Picture set means:

1. Stored collections
   
2. Stored date periods
   
3. A date period which can be entered
   
4. A search key like used in "Global search" (which doesn't work in the prod. version but is already fixed in dev. version)
   
5. And possibly: stored Filter Wizard filter settings (dev. version already can load/save filter settings). But, this might be impossible due to infinite loops in source set definitions.
   

The picture set will be selectable in the Filter Wizard dialog box and even better, you can go into "Browse by Date" or "Collections" and open the Filter Wizard with the context menu.
