Greengrass V2: Do sub-deployments inherit component versions/config from parent deployments?

Hi,

We are looking at using GG subdeployments to help manage different GG deployment configurations across different groups of sensors. My question is: do subdeployments inherit deployment configs from it's parent, and overwrite these if the component is present in the subdeployment?

Alternatively, are different deployments targeting different thing groups a better approach here? If we were to go down this route, is there any way to support "inheritance" of component configs as described above?
