Are there any MSWORD 2016 forum ideas for a macro or some sort of automation to order/reorder a ToC into Heading Level 1 alphabetic order?

I am creating a very large document of instructions. I would like the Table of Contents to be in alphabetic order for each Heading Level 1.

Is there any way this can happen either - as I go automatically, or, via a macro button? OR, Will I have to [manually alphabetically place] each section of the entire document?

Kinda weird, I know, but it's what I would like to achieve with as little manual work as possible.

Thanks, Dekade
