Is your feature request related to a problem? Please describe.
In our case, our collection of users have the email address of the user as the document ID. When I create a table, I can add a column using the "Metadata - ID" field type to display that information, but when I want to search for a specific email you cannot do it because it is not a field, I guess.

Describe the solution you'd like
Extend the filter options to search by the Metadata - ID / Row's ID.

Describe alternatives you've considered
Maybe adding a new field type for "Mapping" other fields. So if I have a field for First Name and other for Last Name, with this field I can join both to have the full name. Of course, this type of field will be only internal/visually and not do any change in Firestore.

Regards.
