It would be interesting to know more about your workflow and the need for a specific order of instruments.

First: Instruments can be re-ordered using the move/copy command and their labels customized.

Second: If it's a processing issue, multiple instruments can be placed onto any single track and perform as a bus with up to 4 effects processing all of the instruments while having panning and volume control over each individual instrument. For Example, in BIAB, there can be two (or more) acoustic guitars occupying the same Mixer Channel and playing simultaneously, panned hard left and right and their volume levels adjusted to balance the mix. Both guitars would share the same high pass filter, reverb and eq settings.

Third: I don't follow that the Bar Settings order sequence being exactly the same as the Mixer 8 Legacy Tracks order is clumsy or confusing.
