Paste multiple values into Pick List when adding Additional fields?

Paste multiple values into Pick List when adding Additional fields?

As the title says is it possible by some sort of wizardry to do this, either by an option I've missed or going into the back end databases and pasting them in?

I have hundreds of options i need to add per Field entered, copying and pasting them in one at a time will take an aweful long time?

Thanks in advance for any help.

Cheers
