The feature
It would be useful to have an option to control which albums are used when generating “On This Day” memories.

Currently, “On This Day” memories can include assets from across the entire library. For users with large libraries containing screenshots, downloaded images, work photos, miscellaneous imports, or other assets that they don't necessarily want appearing in memories, this can add a lot of noise.

I would like an option in the Memories settings to select one or more albums as sources for “On This Day” memories.
For example:
Include assets from Family Photos
Include assets from Camera Roll
Include assets from Travel
Ignore assets that are not contained in one of the selected albums

The setting could work as an album inclusion filter, where an asset is eligible for “On This Day” only if it belongs to at least one of the selected albums.
Ideally, the default behavior would remain unchanged (All assets) so existing users are unaffected.

Why this would be useful
Albums are often already used to identify the photos that users actually care about. Allowing Memories to use albums as a source/filter would make “On This Day” significantly more relevant without requiring users to individually hide or exclude unwanted assets.

This would be especially useful for libraries containing a mixture of personal photos, screenshots, downloads, externally imported libraries, work-related images, and other content.

It could also provide a foundation for more advanced Memories filtering in the future, such as:
Memories → On This Day → Sources
All assets
Only selected albums
Exclude selected albums
