Invoking a CronJob

Hello,

Is there a way that another application can invoke a CronJob on demand? For example is there a pre-built REST service to invoke a CronJob, or some other means?

The other application would not have access to Hybris code base and can only work with our application through some integration point.

I understand we can build such a REST service ourselves but I am curious if something like this already exists out of the box.

Thanks!
