Section action to add contacts to a participants detail

Hello all,

I am trying to create a process that can add a selection of contacts to a participants detail by picking select all and then clicking on the action in the actions drop down. I've gotten the process to start but it only grabs 30 records at once. 

I know that this is due to Creatio only loading so many records at once as a way to not stress the system too much. However, I need a way to collect more than 30 records. I'm trying to figure out a way to get Creatio to load the records once I've triggered the process.

It's fine if there's a delay while Creatio loads the records, I can always put up a message about how it may take some time. I just need to get the records.
