It may be too late now, but just for future planning: you can create custom blocks for pre-tied aisles as long as there aren't more than two letters (CL, GS, SC, etc.. don't usually get pre-tied anyway, so that's really a non-issue). If you're pre-tying the planogram for B17, you'd create a custom block for TB17 to sort it during the unload.
Try to coordinate with the leader who pre-ties the sets so you can create custom blocks for those pre-tied aisles each time. That way, your unload team just needs to sort by custom block like they always have rather than looking at the aisle itself. You can group the aisles by valley or two if there isn't enough freight coming in for each individual aisle, which still allows you to drop pallets in front of specific aisles/valleys to get pushed when they're set.
Most stores don't use all of their custom blocks anyway, so there should be more than enough to set aside for the larger sets that are pre-tied. You'd just go in afterward or before the next set to adjust them as needed.
