Support 0.3 mm nozzle?

I bought a set of 0.6 and 0.3 mm nozzles for my M300 Dual some time ago. It is possible to print many materials with 0.6 nozzle but there are no settings for 0.3 mm nozzle.

0,3 mm nozzle would help with jobs where better accuracy is important.
Are you working on printing profiles for 0,3 mm nozzle?
It would be so nice to have the ability to print at least PET-G (single and dual mode) with better accuracy.
