RB-DMX1 - Still not W/A/UV Support

Hello Pioneer. There have been several requests for the ability to control white, amber and UV channels going back at least 3 years and it's still not available.

All the replies from Pioneer seem to be "we hope to support additional channels in the future", which doesn't really mean anything.

Several years on from when this was first requested, is anything likely to change in the near future?

RGB is so.... yesterday.

Thanks.
