Adaptive setting - can it be customized?

The adaptive setting seems to perform the same level of interpolation as 1m, as far as I can tell. I run a 50hz screen.

I currently use 1.5m (less artifacts) because it produces less artifacts than 1.m. I prefer the smoothness of 1m, but have to use 1.5m as I prefer a small amount of judder instead of artifacts.

My question is: is there a way to make adaptive setting more adaptive. I would have thought this setting would dynamically adjust the interpolation mode based on the content it was processing.

I would like it if it could perform a level of 1m, but then drop to 1.5m if interpolation was going to produce artifacts.

Can this be done? Is it possible to use a custom script to achieve something like this?

Many thanks.
