Macro/Plugin to assign new documents with a unique reference number

Question

General overview:
The plugin creates a Macro, that can be used to assign new documents in Confluence with a unique document number.

Macro would do something like this:

IR – Incident Report:
The structure of the document number is:
XX-YYYY-dtDDHHMM where dt = Document Type

Functional limitations:
The document number is to be generated on initial save of the document and should not update if changes are made at a later time.

Any ideas how I can achieve this?

Thanks for the guidance James. I will look into the template option you mentioned.

If you are tied to the existing format, then the only way I can think of achieving this is as I outlined above.

An easier option for a unique reference number would be to use the Page ID.

Use case - It would be used to assign a unique reference number to a document in the existing company format. Think along the lines of a case or doc reference number you might see on a headed letter (see example below).
