Ability to filter webhook triggers

I am trying to filter the webhook trigger based on a merge request

As the webhook for merge events shows.

Merge request events
This URL will be triggered when a merge request is created/updated/merged

Is there anyway I can have it only trigger to a url based on created or updated

and then have another webhook url that would execute only on merged?
Or if this is not possible is there anyway to just take merged out of the trigger actions so it would only trigger on created / updated

Appreciate any guidance I couldn’t seem to find anything on my searching.
