New explorer / explorer search / speciality

Whilst looking for hidden collectables today, I thought it would be nice if there was another way to find them, than just the fairy fire buff that shows them all.

How about adding a speciality for an explorer / geo, or a new search that identifies a collectable on your island, and flags it the same way as the fairy fire does, but just for one item. Flag remains for 5 minutes as it does now.

Would give them something else to do that also helps with collectable quality of life, but not break anything?

Just an idea, but the fairy fire buff could be added to the Artifact Search instead of Fish Platters...

Would be a lot more useful that fish platters and sandwiches
