[CQ-Contest] Question about CQWW rules

[Guido Tedeschi]

Hi all,
    is it possible for an operator to operate some hours from a
multi-operator team (his callsign will be listed in summary sheet) and also
make some qso from home with his callsign and send the log only as control
log (his log)?
Example:
iz2xxx will operate for 20 hours from multi-single team ix2x and his call
will be in the operators list of ix2x
iz2xxx will go back to home and operate the last 12 hours of contest with
his call and will send the log of iz2xxx as control log
Is this possible or not?
Thanks, 73 and see you in the CQWW
Guido, ik2bcp
