OK, I can make it work using for example:

AddHandler fcgid-example1 .fcgi
AddHandler fcgid-example2 .fcgi2

Action fcgid-example1 /fcgi/wrapper virtual
Action fcgid-example2 /fcgi/wrapper2 virtual

<Location /fcgi/>
    SetHandler fcgid-script
    Options +ExecCGI
</Location>

So now the question is: do we need the FCGIWrapper directive at all?
