G’day word forum

I’m having some trouble with a document I’m preparing and would appreciate any insight I could get. I’m presently writing my thesis and finding it rather difficult to get my table of contents methodology explanation to reflect my algorithm diagrams and associated file structure.


Specifically I’m wondering if, using word, it is possible to:
A. ‘Nest’ new numbering (Blue) within an existing numbering (Green) and have the table of contents reflect such (see below), and;
B. Add the word ‘Stage’ in front of numbered headings (see red)

It may be important to note that under headings there may be subheadings, see Orange.

1. Abstract
2. Introduction
3. Literature Review
3.1. LiDAR scanning
3.1.1. Terrestrial
3.1.2. Airborne
3.2. Allometric Calculations
4. Method
Stage 1: Procedure 1 Title
Stage 2: Procedure 2 Title
Stage 3: Procedure 3 Title
Stage 4: Procedure 4 Title
Stage 5: Procedure 5 Title
5. Results
6. Discussion
7. Conclusion

If one or both of these things are possible is anyone able to let us know how (procedurally speaking) to achieve this?

Cheers

Matt
