Change label string

Hello,

Sometimes we don't understand the meaning of the string because the string is much bigger than space label, besides, the horizontal aling is "center". We have set spanish language.

Is it possible to change the label string? I know we can change the softkeys label, but I cannot change or I haven't found the way to change the string e.g. when we are in a call and we do the transfer, you see "Desvio Llamada", etc.

Thanks,
