can I convert a subcategory to a category? Category fld only displays 2nd part of subcat name (Q Mac

Upon importing from Mac Quicken 2007, all that's visible on-screen in the category field is the subcategory name (not the full category:subcategory name) for each transaction. Is there a way to display the complete name? Or to convert the subcategory to its own category, in order to display the full name?
