You can use the currency box to specify nm instead of a currency symbol. But the rest cannot be done in the inspector's data tab.
You can, however, define calculation fields that produce these formats.
Thanks for that. I have tried it out and I had to use the decimal formatting in order to place the nm at the end of the string. The curency formatting places the symbol at the begining. I will look into how to define fields, thanks.
One of the options for currency allows you to put the currency symbol after the digits instead of before. I hadn't noticed that the decimal formatting option also has this same option.
