JSON webhook to copy a ticket

I created a Webhook with a JSON body that creates a ticket by copying some values from the original ticket.

This is the code:

{
  "ticket": {
    "status": "open",
    "group_id": 24993349,
    "requester_id": 947291444,
    "tags": ["{{ticket.tags}}", "ticket_clone_task"],
    "subject": "{{ticket.title}}", 
    "custom_fields": [{"id": 23079830, "value": "{{ticket.ticket_field_23079830}}"}],
    "comment": {"body": "{{ticket.comments_formatted}}"}
  }
}

However, I need to copy ALL the CUSTOM FIELDS from the original ticket.

In the community I found how to individually copy the custom fields with this line of code:

"custom_fields": [{"id": 23079830, "value": "{{ticket.ticket_field_23079830}}"}],

My question is: Is there a way that copies all the custom fields? Or do I have to insert all the individual custom fields?

Thank you for your help.
