Multiple Session Boxes – One Controller? Any chance?

Hi. i am trying to create a script, where i can move 4 different session boxes instead of one. the goal is to have 4 columns of my Launchpad representing 4 session boxes, each with a height of 8 and a width of 1. i want to scroll through the column only vertically, the horizontal position of each box should be fixed/locked. so i can navigate through the whole clip-list on each track. Is this even possible?
i managed to have multiple session boxes visible by loading multiple scripts for one controller, but i am only able to control one of the scripts in ableton. the other thing i managed to work was having one script with multiple session boxes in different modes, but there it seems that i can have only one session box at a time, making it impossible to press play in two different boxes at the same time.
