Please tell us more about your question or problem

My company has several applications, and an internal company-common library. company-common has a bunch of common utilities and components that are used throughout out apps.

company-common has a dependency (lets call it 3rd-party-ui-lib that is a real problem child. They follow semantic-versioning loosely, patches occasionally contain breaking changes, minor releases are often breaking, and we find that if company-common and application-1 have different versions of 3rd-pary-ui-lib, weird shit happens.

I'd like a way to configure renovate to update company-common normally (that is, keep 3rd-party-ui-lib up to date with it's latest release on npm. For application-[1,2,3], I'd like renovate to use the versions defined in company-common`, and then fallback to npm.

That way, we can have renovate update company-common, verify it, release it, then have renovate update application-1 with the new 3rd-party-ui-lib only after its been verified and released.
