+1 on having a way to do this via the triggers UI 

We have partners who sometimes work with multiple customers at a time. So they may be submitting support tickets from the same email but for different customers. We collect the customer ID in our support form and our use case would be to have the ability to associate specific partners to specific Zendesk orgs by the customer ID and not by their email domain. However the current trigger UI only allows you to specify whether or not that numeric field is there.
