HRD said 9 months ago they were going to address and fix it . those messages were and still are on this community ... but just like the experience I have had with them when I was asking for information and trying to purchase their product it just didn't happen. Lots of talk of what the future will show but no action.
Maybe things have changed ... but this thread is indicating nothing has changed on their side of the fence.
For digimode programs that support the HRD TCP protocol, SM6k supports slice based listeners. That's the more traditional implementation. Connect to one of the slice based listeners and the digimode program will only have access to that one slice.
If your digimode program of choice happens to be DM780, it's even easier. Simply switch a slice into DIGU mode and Slice Master 6000 will configure and launch DM780 to work with that slice. Switch back to CW mode and DM780 will close only to be replaced by CW Skimmer.
