Add an empty JobHandle as a dependency to other jobs

Conceptually, jobA needs to wait for jobB, but jobB is not actually a job. I need to do some work in a compute shader and return an empty JobHandle that has its Complete() method called when the compute shader has finished its calculations. Is there a way to make something like that work?

Code (CSharp):

1. JobHandle handle = new JobHandle();
2. // make other jobs depend on this empty job handle
3. return handle;
4.  
5. // Somewhere else in code call complete after a compute shader has finished
6. handle.Complete();
