Max 16 webhooks issues stripe

I have 40 sites with GD, I have set-up the sites fine and they take payments, publish OK etc but you can only add 16 webhooks with stripe. I only have 1 business that owns all thees sites so I cant setup another stripe account. I have raised this with stripe and got the message below;

“Thanks for reaching out, I’m happy to help! Unfortunately, it is not possible for us to change the maximum number of webhook endpoints per account.

Another possibility would be to set a single endpoint in your account settings, and use that endpoint to dispatch the received events to all your “real” endpoints.”

I have no idea what they are advising or “real” endpoints, any ideas?
