tmux mouse scrolling without altering copy/paste?

I'm having difficulty finding an explanation for allowing the OS default copy/paste capabilities (i.e. highlight a portion of text and then use standard shortcut or right-click menu) and allow mouse scrolling at the same time. Mouse mode turns on tmux's own copy/paste system, but leaving it off removes the mouse scrolling. As I'm switching between an IDE, browser, and terminal with tmux I would like the controls to be consistent between all of them. Is there a way to have the standard OS copy/paste controls while also allowing the mouse to scroll in tmux? _(Note: I originally asked, but deleted, this question on SO. I decided it was more appropriate here.)_
