How do I mix sections of multiple settings?

[thateffendude]

What is the easiest way to mix parts of multiple settings?
For example, we are about to start a savage worlds game and the guy running the game came up with a unique setting. He borrowed the spellcasting from hellfrost and the black powder from 50 fathoms. Plus he generated his own content. I can add all the settings and preclude EVERYTHING in the editor, but that seems silly. And when I add stuff from the other settings exactly as they are, it complains about duplicates. So I copy them and rename them but there is alot and copy and rename is a pain in the butt.

Please help.

Also, he is using the no power points of hellfrost but created an arcane background that does use power points. Is there a way I can do both?

Lastly, can I remove the display of the casting modifier from spells in the no power points displays?
