Performance mode limited to sample tracks?

I’ve noticed the mute list in pattern mode will only show 8 tracks at a time, but will switch to 9-16 if the cursor is at column 9 or above. This is cumbersome but workable.

But I’ve also noticed that performance page will only work the first 8 tracks and there is no way to switch to 9-16 as far as I can tell. Is there any plans to allow performance for the upper tracks?
