merging cuelists

Is there a easy way to merge a entire cuelist to a existing cuelist. I have been movung the cuelist to a fader, then selecting the cues then copying to the existing cuelist. This is how i do it.
(Cuelist 453 move to playback fader 5)
Open fader 5 by hitting choose choose.
Then (cue 1 thru 25 copy to list 454 cue 17.1 enter)
Is there a way to make this simple. Like cuelist 453 merge to cuelist 454?
