How to move funds from one depot to another

[S. Seide]

Hello,

i have a question one how to move funds/shares between two accounts. For money its easy - there is a special
action for that adding the out and in for each account. But how about funds/shares? I can remove them from 
the old account and add them to the new one only it seems. But doing this completely messes up the investment reports.
After the move i have two lines there - one for the removed with a total loss and another one for the new 
account with a profit measured in astronomical units (something around 343436363636363%)

Is there a way to do it "right" and have correct reports?

Thanks,
Stefan Seide
