Can I use a different file than .travis.yml?

[njlr]

Can I specify (for example in the web UI) that I want to use a different file for my CI task definition?

For example, .travis.override.yml

Allow repositories to specify where `.travis.yml` should be found

I’d like to keep repository free from CI configuration noise. e.g. Appveyor CI allows to provide an URL to YAML config on project settings in Appveyor GUI. It’s great also for other reason, as that way I can easily share common config among projects that require same setup. Is there any way to achieve that with Travis CI? If not, is it somewhere on a roadmap?
