Is it possible to combine cron-scheduled builds and checks about github changes?

Hi all,

I’ve a quite big project, which takes long time to build. Because of that, I don’t want it to be rebuilt upon every Github pushed change. At the same time, I’d like to build it automatically every day, if there have been GitHub changes since the last build. Scheduling a daily rebuild doesn’t seem to achieve such a result, the repo is rebuild daily anyway, even if the code on GH is exactly the same as the day before. Rebuilding a big codebase that didn’t change since the last successful build isn’t very good.

Is there a way to obtain that in Travis? Should I file a new feature request?

Thanks in advance,
