I am currently adding the Abbreviations section by using
\nameref in the TOC to circumvent the problem with
glossaries packages to include the the glossary. This is using the code as shown below, which also keeps the abbreviation sections un-numbered in the index.
Is there a similar way to add the TOC in TOC page, as the current TOC doesn't do so by default. Document class being used is article. I have roman numerals for rest of the body while the main sections are all arabic numbered. So also expect to see TOC in TOC with corresponding roman numerals of the page.
