I know it is not what you want it to be, but at least you can edit and change it. The other thing you can do is entering the data as time, so as "32:45:10". The only thing is that you will have to multiply the figures with 12 in order to use them in your calculations and you cannot edit them. So in cell A1 you put the figure 32:45:10 and when you need the sinus of it you say in cell B1 "=SIN(A1*12/180*PI())".
