Use CRM Variable in webhook URLtoNotify

Use CRM Variable in webhook URLtoNotify

I have a CRM variable that I use to set the environment specific portion of the URL. This works great in custom functions, but is there a way to use it in a webhook URL to Notify config?

I was hoping for something like using values in an email template,  ${General.Orchestrate Environment}.

Is my only other option to always use a function instead of a webhook?

Thanks
