I have a document where I created styles for a main heading and a sub headings. I need the TOC to number the TOC as below, the problem is that the document is not using numbering. I also need it the points a and b to aligned under the text of the previous point.



Example:


Section A: blah blah (Main Title)

Section A1-a: Care and Treatment (Sub Title)
Sub Sub Heading: Results of Testing



The TOC needs to look like this:


Section A: - doesn't need a number
i. Care and Treatment (Roman numeral)
ii. Testing

a. Results of Testing
b. conclusion
iii. Next steps
