interact_plot geom_ribbon

I am wondering if there is a way to change the geom_ribbon default for confidence intervals in interact_plot ? I would like to have dashed lines instead to illustrate confidence intervals, and not to rely on colors. I think in most social science journals colors are not reproduced in published articles.

Start by locating the interact_plot entry point and examining how its geom_ribbon confidence intervals are configured. Check the existing documentation and examples for confidence-interval options; done should mean users can represent these intervals with dashed lines rather than relying only on color.
