Only indirectly, AFAIK. Since it's a TV show, I assume there are dividers for each episode. If you right-click on a divider, you can copy the cast for just that section and paste it (append at the end). You can then click on the divider and while keeping the mouse pressed move it up the total cast list until it sits where it should be. Next, delete the original divider with the incomplete cast below it.

EDIT: on second reading, I think I misread your question. I now understand you copied the lists but want to add individual credits to them. Just enter them, left-click on your entry and hold (keep the left mouse button pressed), and move it up until it sits where it should be.

Hope this helps!

Also check out Tom Gaines's TV cast and crew project over here.

Using his cinematic collection viewer, you can download 100's of complete cast and crew updates for various tvshows. You can copy those from within the plugin, and paste them in DVD Profiler.

Also, in edit mode, you can select any actor or crew member from the available list on the left, and drag it to the desired position on the right.

This is a lot faster as adding it to the end and then draging it to the desired position.

I learn something new every day.
Thanks Chris. 

Seconded - this old dog just got taught a new trick

Thank you both so much.

I've been doing this for a while and the only problem I have encountered is in the Cast section. I find if I drag/drop to insert cast it causes a fault when I try to do the same in Crew (the crew lists jump up and down and you can't add anything). I have to save what I've done on the cast and then go back in to do the crew.

Thank you Pantheon. Now that I have my new supply...green arrows all around!

I really wished I had tried this or knew of it before editing all those Tales from the Crypt season sets. That 'drag up and drop in place' took forever.

Thanks for spreading the word, Chris!
