There are at least two format built-in functions that would be very helpfull:
1. Date Format. We can change the format for all dates from Service Center, but it would be nice to have a built-in function for this. The current solution it's not very flexible.
2. Currency Format. The current function does not allow the user to choose the symbol position, so it will always be placed before the value. Many european countrys place the symbol after the value (like Portugal).
