Put on all pages automatically?

Can this be added to all pages as defined in the settings – “Posts , Pages , Events”.?

By adding to to all pages automatically – we then only have to update the standard events as described by Facebook (https://www.facebook.com/business/help/402791146561655), with a small addition to the facebook pixel.

Otherwise, you have to remember to add this to all: pages; posts; and events, every time.

Thank You
