How to trigger program rules on a list of event

We have recently added program rules setting values to some data element to an existing program with some thousand events. Those works well, and each time we open a specific event we see them computed and the values correctly set in the related Data Elements.

The problem is now that we would like to “trigger” the rules on all our events. Our logic would be to call the API and iterate using a small script, but we’re unsure how to “force” DHIS2 to trigger program rules on a single event - any tips here?
