In my Studiometry setup, Expense is the default Debt/Credit type for new items. When a new Debt/Credit is created, the input field starts in the Description: field (which is desireable).
I have a number of shorthand abbreviations for different kinds of Hourly labor categories. When I use these abbreviations, the result is an Expense item which needs to be converted to Hourly type. It's not a big deal, but it would be helpful if the Abbreviation database could also remember the Debt/Credit Type associated with an abbreviation, and apply it automatically when a new item is created.
