"I seriously doubt that it would generate enough interest among FTM users to justify the expenditure of those resources needed to implement it."
Actually, the cost of implementation would be trivial. It's mathematically based and easily coded. Even a novice programmer could add the capability in very little time. It's that simple.
Anyway, I take it that you don't see anything of value in the numbering system that would merit an enhancement request. Thanks for being the first to answer the question. ;)
