Procedure
Aircraft X was refueling eastbound with Aircraft Y and Aircraft Z.  Aircraft X's data block reflected FL270B300 and RVSM capable.  The Aircraft Y and Aircraft Z aircraft flight plans were non-RVSM capable thus making the Aircraft X's flight during the refueling status non-RVSM as well.  Aircraft X's remarks stated FL270B290 so I don't know why it was changed to 4000 feet block unless it was someone's misguided attempt to protect for the non-RVSM status.  We corrected the equipment modifier for the Aircraft X flight to reflect it's non-RVSM status and informed the next controller that Aircraft X was RVSM capable and only the refueling aircraft were not.  We also informed Aircraft X to let the controller know when they split up that he was RVSM capable.Correctly reflect in the flight plan the status of all aircraft flying in a block formation of its RVSM status.
ZME Controller describes a refueling flight that is non-RVSM capable due to the two aircraft that are refueling are not capable.
