Question about new workflows registration

I have quite dynamic range of workflows that are stored outside of this library, but when new workflow is created, I need to register it. In multiple instance environment it is not an obvious task (we pull new workflows each 10 minutes, but is not an optimal resolution as some instances can hang on this workflow with error about unknown workflow).

Is there any place that I can hook to it and then check if new workflow should be registered and just do it? something like WorkflowNotRegistered event that would be thrown and could be implemented on my side?

Start by tracing workflow registration and the handling of unknown workflows in the .NET workflow engine. Compare that path with the described ten-minute external pull and determine where a hook or event could observe newly created workflows across multiple instances; done means the registration behavior and callback scope are clearly defined.
