Advancing build number counter?

Is there a way to increment build number by more than one ? I’ve looked through the API and i don’t think I’ve found it.

This came up in a project that has already thousands of builds made, and needs to be effectively forked, and keeping the current build numbers would be a nice to have.

Just splitting things up into a separate github repository obviously resets the travis counter to one. If i could trigger next build with +6000 that would solve my problem - Jenkins for instance has a plugin to do that.
