Since each rack receives a fixed type of items, can't you just modify their zoneIDs (which are currently used to assign the totes) accordingly?
If the racks are to receive mixed types of items in the future, based on what logic would the other types be assign to totes?
Also, you should run the subflow tokens one at a time, otherwise the AGV doesn't actually stop when it is loaded.
Which tote is used is currently determined when the subflow tokens are created and depends on the zoneID of the rack.
You can move this into the subflow, after an item was found. First get the index of the tote based on the item label, then get a reference to that tote. Before the actual load operation, you can then also implement a capacity check in a Decide activity.
If more than one item can be loaded at a station, the token could also loop back to the "Find Item" activity after an item was unloaded into the tote.
If the loading subflow aborts because the tote capacity was reached, the "found" item is still part of the array causing the operator to "unload" it together with the other items, despite it still being in the rack.
If the token leaves the subflow through the decide activity, you have to remove the first entry in the item array. (Either use the "Array" options in the Assigns Labels activity or use a Custom Code activity with "token.items.shift()".)
