question

If you're wanting to pull by BOTH partition ID 1 and partition ID 2 from the same Pull from List activity, you cannot currently do that. Instead you would push them to one partition and use labels or a column on the List to specify whether the entries are of type 1 or type 2. Then you encode it in your Query:

WHERE partID == 1 OR partID == 2

If you want each token that enters the Pull from List to pull from EITHER partition ID 1 or partition ID 2, then your code in the Partition ID field could be something like:

duniform(1, 2)

or conditionally:

token.myPartID = 10 ? 1 : 2 //ie if token.myPartID < 10, return 1, else return 2
