Cancellation of time ticket confirmations at a time

Hi

My client is using co11n for confirmation of Production ordrs.

In one order they will have 20 Operations.. daily they will do partial confirm qty.

They want to cancell confirmations of some of the operations at a time is it possible

Presently they are using CO13 biu in this we can cancel cofirmations one by one only..System is not allowing to select another confirmation at a time.

Please suggest.

Regards,
