Format Numbering to 001

[Bursal]

I am developing a Policies & Procedures manual for a community organisation. The manual consists of:

Cover page and blank page with a next page section break
TOC with a header and a next page section break


Policy section – each policy has:
Heading with outline number, is it possible to format heading number to start at 001 rather than 1? For example 001 XYZ Policy
Page footer with heading number and page number should be 001 – 1
Followed by next page section break.
TOC to reflect the heading number and page number, for example:
001 XYZ Policy 001-1

I don’t if it is possible format the 001 numbered outline heading or the footer numbering and if so how can I do it?.

Thank you for reading my post and hope you can help me.
