You can preserve the order within a folder track when clicking on the wrench icon in the channel list
and select "Preserve order of channels with folder track".
See my pic: The "DRUMS" bus is located in a drum folder together witth an impact track (which results in several impact output channels in the console).
Not perferct for everything, but it works if:
a) you put your bus into a folder. The position of the bus in the console depends on the position within the folder track.
b) Note: The "Preserve order option" takes precedence over the "Keep bus channels to the right" option!
