Is there any way I can choose which IP I want a site on without giving it a dedicated IP in WHM?

Have a sort of solution. I can just change the main IP before I add a site, then it will add it to that IP without making it dedicated. It's a bit of a slow way to do it though, so I would love to hear if anybody knows of a better way. Even outside of WHM.

You mean you want to setup a SECOND SHARED IP correct? So you can set a group of sites to an IP address that is not the main shared IP. Yes, you can actually setup as many shared IP's as you want in the WHM. It all revolves around creating a dummy reseller account.
