Select Track in box

I hope I have this right;
I have a box consisting of 8 columns
I know I can use left and right to move the tracks, that works but its not how my workflow operates. I have 7 tracks grouped giving a total of 8 tracks. These are logically grouped into instruments etc. There are 8 of these groups. I want to select a box (using the bottom row of 8 keypads to move 8 tracks at time) and then be able to use the 2nd row of keypads to highlight a track within that box ie pressing the 2nd keypad should select the 2nd track within the box.
I am unable to work out how to do that…highlight doesnt seem to provide a box relative option and uses absolute positioning?

Thanks for any help
Mark
