How to assign release strategy to plant

Hello,

We have our release strategy at the purchase requisition level for several plants.  With a new plant just added, how do I assign the same release strategy to it as another  plant? I looked in SPRO and I can't find anything that has a plant assignment.  We have 1 release group, 3 release codes, regular release indicators, and 2 release strategies.  When I create a  PR for the new plant the Release strategy doesn't kick in.

Thank you.
