Source: Discord thread

When using any of the Doctor commands, it's possible to specify the scope as the current note of the whole workspace. You cannot, however, target a specific set of notes.

Describe the solution you'd like

• an ability to specify a hierarchy as Doctor's scope using regex (in the same way it's used in refactoring flow: daily.journal.(\d{4}).(\d{2})$)
• show a preview (similar to the refactor preview) of notes that will be affected by the Doctor command

Describe alternatives you've considered

No easy alternatives come to mind.

Additional context

If implemented, this feature will alleviate the pain of the following issue (almost to the point that I would consider #1919 as very low value):

• 1919
