I have a GDG generation on tape and each day I wish to apend to the same GDG generation for the whole month. Can anyone tell me how I can do this most efficiently.

You can use disp=mod, but remember, if your job abends while adding to the tape you can't just re-run the job.

When disp=mod is used it's usual to backup the tape before you attempt to add to it. Then, if the job abends you use the backup to reconstruct.
