Categories, Classes and Supercategories?

[Rongoldby]

I have used the UK version of Quicken very successfully for well over 20 years the latest version being Quicken 2004. For tracking family finances where both joint accounts and sole accounts exist the concept of Class within Quicken has been immensely useful, I might say for my purposes essential. As far as I can see from browsing this forum and the information available MMEX supports categories and subcategories but does it also support Classes in the sense defined in Quicken?
For certain tax forms concerned with UK Inheritance Tax the authorities require annual income and expenses to be tabulated under a very limited number of broad headings and for this purpose the use of Quicken Supercategories is ideal as the allocation of each Category to a superior Supercategory allows basic data entry to be simpler and intuitive being based on alphabetic categories rather than a tree of categories, sub and sub sub categories! Once again - does MMEX support such Supercategories?
I hope that someone who has switched from Quicken to MMEX may be able to answer these questions or perhaps to suggest possible workarounds. Even with workarounds I would guess that data migration might be a very tiresome chore.

MMEX supports Tags which are equivalent to Quicken Classes (I think Quicken now calls these Tags also). I'm not sure what the "Supercategory" concept is.
