SharePoint Term Store Managed Metadata

I would like Power Query connection to SharePoint improved so it can have better access to our Global Term Store. The TaxonomyHiddenList feature does not provide enough details from the Term Store. For example, it does not provide the "Synonyms" and "Description". I would also like to see improvement to the Hierarchy paths. Our global term store has several levels between 2 to 4. The "TaxonomyHiddenList" only shows lowest level an its immediate parent. This make is difficult to identify the logically groups of terms from our term store.
