Feature request: Set sidebar for issue detail pages

[mathysp]

I'm currently building a site with a lot of different sidebars: one for the homepage, one for the shop, a couple for certain areas, and of course there is a specific sidebar made for the Magazines & issues.

Now, currently there does not seem to be a way to choose which sidebar should be shown on an issue detail page, it just defaults to the default sidebar. It would be great if this was available as an option through the settings.

A possible work around would be to use the main sidebar to hold the widget issues. But this would not be a good solution.
