Duplicating monsters?

[kodarr]

I have created a goblin in the dangers. I wanted to copy the goblin multiple times and adjusting it by adding levels of classes or slight change of equipment and levels to make a subcategories under goblin. However, I don't want to re add all the info over and over for goblin. But I'm not finding any way to copy a creature and paste a duplicate of one.

Is this something that can be done? Or would I have to re add the goblin over and over retyping everything from ac to ecology.
