Graph Deployments to Reference Existing Model Deployments

[cccs-km]

Hi All,
I have been looking through the documentation in Seldon-Core, specifically for Graph deployments where we can pipeline models together. I have been unable to find whether a Graph Deployment can reference already existing Model deployments and CRDs. Is this possible?

Ie:
I already have models A, B, and C, deployed separately in their own deployment file.
I would like to specify a new Graph Deployment that references the existing A, B, and C models in the order of:
inputs ==> A ==> B ==> C ==> outputs
