Redesignation of Custom Fields in Contact Forms

I’m using Zapier to assign Contact Form responses to cells in the Google Sheet that I use to track business. It does a great job with the standard fields. However, I’m running into issues when using different forms, which each have different additional custom fields. Is it possible to redesignate the custom field numbers so that they can be properly assigned via Zapier? For example, in my wedding event form, Custom 2 is the Event Start Time. However, in my Quinceanera, Custom 2 comes out to be the name of the Quinceanera. In the Corporate form, Custom 2 is the Referral. Is there a way to list ALL of the custom fields and make each one unique for use in different Contact Forms?
