microsoft wordmicrosoft-word-2010

In Microsoft Word I used the Multi-level list option to create heading 1 Heading, 1.1 Heading, 1.1.1 Heading etc.

I would like to add a preface that is recognised as a heading (so that it will appear in the table of contents) but for the preface sections not to have any number prefix in the TOC.

Also whilst the page numbers are correct (using section breaks restarting page numbering to 1) however I would like my actual content headings to start at 1 (which in this example is currently 4 Configurable service options).

I am getting the below:

Where as I want the contents to be:

Revision Control......................................................ii
Overview..............................................................ii
Background Information................................................ii

1 Configurable service options.........................................1
1.1 User Changes option..............................................1
1.2 User Selects Pre-requisite option................................1
1.3 Billing Cycle is Changed.........................................1

/* snip */

2 Cart Validation On Submission
2.1 User Submits Valid Cart..........................................1
2.2 Users Submits Cart with Option(s) Whose Price Has Changed........1
3 Service Order Processing.............................................2
3.1 Use Cases........................................................2
3.1.1 Cart is validated, and assuming OK a service order created.....2


Is this possible and if so how please?
