Bulk API Webhook for Profile Updates

We have over 60 profile fields.  We have set up a webhook to get updates on Profile fields to sync back to Salesforce.  When a new user is created the webhook sends a payload for each of the profile fields (60+ individual payloads for one person).  We are only interested in 5 of those 60+ fields.  

Can a webhook be added to send a bulk update? One payload per user, and include any field that was updated.  This would greatly simplify the API processing.
