S2 extraction from S2-O3 Dual narrowband filters

since the release of ASKARs dual narrowband filters with S2-O3 and Ha-O3 https://www.askarlens.com/index.php/6nmcolourmagic/308.html Hubble Palette will be easily possible to shot with an OSC.

For now S2 extraction is possible (not yet tested by myself but soon to come) with the "extract Ha from Ha-O3" algorithm. But the result would probably be better with a dedicated algorithm for that.

Are there plans for a possible feature for that?

SII falls into the red spectrum the OSC records, so it'll not help to have a different algorithm as there's no way to distinguish wavelengths from data that is specific for SII or Ha when both are recorded mainly via the red filtered pixels on the sensor. If you really want only SII and Ha, you need specific SII and Ha only filters.
