How to enforce SBT to always fetch sources for project dependencies?

Just getting started w开发者_Go百科ith SBT, and I would like to setup it up to always get sources for dependencies it downloads. Having to add to remember to type withSources() for every dependency declared is only mildly annoying, but the real killer is the dependencies of dependencies problem.

Anybody know a simple switch to turn this on?
