Change callsigns to upper case?

[G0FEI]

I have two callsigns registered (GØFEI - NØFEI) and have set them up in lower case on the welcome page, can they be changed to upper case, also, can zero's be slashed?
Please advise.

Hello,
g0fei to G0FEI will be changed soon (it´s done)

Slashed zero is not used in all countries.
