[Evolution] How can manager more than one google calendards in Evolution?

[Ismael García Fernández <ismael-garcia moviments net>]

Hello

I have more than one google calendars with the same user and I would 
want to be able to manage them from the evolution.

I can see for them, if I add them to the evolution as web page 
calendars, but I can not edit them. If I add them as google calendars, I 
can only see one of them, gifts only it asks the user and it chooses him 
some of the calendars of that user.

How do I have to make it?

Thank,

Ismael
