Either by renaming the current "Tiler" to "DatasetTiler" (or similar), and create a new "GeometryTiler" transformer, that works on individual tiles/geometries.

Or by adding a dropdown or checkbox to "Tiler" that enables tiling of individual tiles/geometries instead of the whole dataset.

In a feature-by-feature workflow it makes sense to have this kind of feature based functionality.

Ah, so you'd like each feature that goes in to come out with its own set of tiles. Feels like this could be an option perhaps on the Tiler we have now?

I currently create this functionality by wrapping the tiler in a custom transformer and publishing the parallel processing Group By.

Then in the main workspace the group by is set to a unique value per feature (ie Counter)

Hmm, what if there was a "group by" on this transformer. Then I think all things are possible?

Group by would be great.

Well, we just added GROUP BY to the Tiler. If you engage the GROUP BY on an attribute that is unique per feature (say made by a Counter xformer upstream) then it should do as desired. Will advise when this is in beta for FME 2017.
