as explained in the P4 Handbook, we have to include some parameters on petition/campaign pages dataLayer:

as a web editor i'd like to have a dropdown on the campaigns backend that lets me pick a value for these fields.

NRO name could be set automatically
campaign name could be dynamic based on the basket (so basically basket selection would filter the campaign names to ones belonging to the selected basket)
