Separating decimals with comma in number column

It would really help in typing in decimals with a numpad to be able to use comma instead of period.
Would you consider making this available?

Also changing the way you use comma vs. period.
In Germany we write it like this 10.000,50€ Not 10,000.50€
The second one is incorrect (wich to my understanding) is not changeable in for now…
