.DotSettings file per Unreal Plugin

Is there a way to have a `.DotSettings` file that is automatically loaded that can be distributed with source but not be specific to the solution?

In this particular case, it would be part of an Unreal plug-in, which does not have its own solution nor its own local `.vcxproj`. Placing it somewhere under the plug-in's directory (such as `Source`) does not seem to work.
