How to create a unique Partition ID from item push to a list?

I have 2 CPU buffers (1001 and 1002) that I want 2 tuggers (Special1 and 2) to be exclusively dedicated to them. I created a unique Process flow (Tugging and Staging Porcess3) for them to pull the full pallets. But I don't know how to identify those items push from those buffers (1001 and 1002) to the FFlats list. I have 3 other tuggers dedicated to the FFlats but they can pull 1001 to 1006. I tried to create labels for the pallets arriving a 1001 and 1002 (Special) then find a partition for that token but it didn't work.

Thanks!

@Ryan Clark

I was able create a partition when 1001 ands 1002 push the full pallets to the FFlats list and made tuggers Special1 and 2 to pull that partition. However, the other 3 Tuggers can't pull that partition even though they are not pulling any particular partition (none).

When pulling entries from a list, only a single partition can be queried at a time, sadly. So you either pull items that belong to a certain partition or items that belong to no partition.

You could instead assign a label to the items that signifies if they are part of the 1001 or 1002 buffers or not. Then use the query field in the Pull from List activity to only pull those belonging to the buffers with the special tuggers. For the others you can leave the query empty to pull any item.

Attached is an example model in which the red operator can only pull items from Queue1, the others from any queue.

Pull over all partitions is possible as a query over the tree structure of a global list. I answered a question for collecting all items of all partitions.
