ARR Vertical Sorting

As it currently stands, ARRs are sorted Alphabetically in each column, but sometimes this isn't ideal. It would be great to have some kind of override for the alphabetical sorting so that you can apply a custom order. The best way from a user perspective could be to add a "sorting override option" which allowed you to just enter a value and the alphabetical order would use the override value, i.e "H" to apply the ordering in the column

Additionally, it would be good if you could add spacers between ARR items vertically, so you could have ARRs sorted into groups vertically as well. That would increase the effeciency of the ARR system, without needing a large number of ARR categories

Yep, I mean vertically within each of those 6 columns cant be sorted
