Running features not found in resources

I'd like to be able to source my feature files externally (the use case is not your typical Android application - it's a custom device and test automation is running as part of some end-user scenarios).

Having .feature files on the local filesystem would work (but a mechanism that would allow me to supply gherkin scripts from a source of my choosing would be better). I've tried running "am instrument -e features [path.to.file]" but it looks like cucumber-android is still looking for a path within resources, not the filesystem.

Curious if this is possible with the current implementation?
