I don't actually know if one exists but it would make my life easier if anyone could think of one.

This question appears to be off-topic. The users who voted to close gave this specific reason:
- "Questions on choosing an ideal word or phrase must include information on how it will be used in order to be answered. For help writing a good word or phrase request, see: About single word requests" – Matt E. Эллен, Mitch, choster, Kristina Lopez, Hellion
It might be a stretch, but perhaps you could say that the subject has already been covered?
- To deal with; treat of: The book covers the feminist movement.
Well, english.stackexchange.com uses Closed when a question has been previously researched/studied.
Besides covered, consider also the following words, which when used figuratively of a field, imply it has been studied or perhaps exhausted: cultivated, crosschecked, consummated, construed, conquered, clarified, circumscribed, chronicled, checked, characterized, catechized, and less suitably, capitulated. For a humorous touch, consider coauthored; eg, “That area has already been coauthored to death”.
