You can use the Sampler to sample a List resource in Process Flow. For example, if you sample a List resource as part of a token label:

You can then use that token label in the Pull from List activity. So you wouldn't use:

List(token.BatchList)

Instead, you would just use:

token.BatchList

You can also use the getactivity() command in a similar way to Model.find(), like this:

getactivity(processFlow, "List2");

Where the first parameter is a reference to the Process Flow that contains the List resource, and the second parameter is a string for the name of the List resource. You can also use a string with the name of the Process Flow for the first parameter if you are using multiple Process Flows or the code where you are using getactivity() does not have a processFlow variable for you to use.

And finally, you can still use just one List, even with multiple categories. In your example in one of the comments, you could still use Partitions to differentiate between the four categories that you are using seperate lists for now. And then you can use a list field to help identify which batch a product is in (1, 2, 3, etc.).

Fields are set up in List Properties (the Advanced button on a List resource). You could use a Label Field if the products have a label on them with their batch number. Otherwise, you would probably need to use an Expression Field to get that information for the products being pushed to the list, depending on how your model is set up.

Then, in the Pull from List, you would identify which category you want to pull from in the Partition ID field, and use the Query field to only pull the batch you need at that time:

WHERE batch = 1

You could also set up a dynamic query with a token label or something. Something like this:

WHERE batch = Puller.batch

Where Puller is a reference to the token (identified in the Puller field in the Pull from List) and batch is a label on that token.
