Assign existing/custom `schedulerName` to StatefulSet

Hey folks!
I have installed CRDB using the operator. I'm using Piraeus as my CSI Provider.
To place pods "as close as possible" to the PVC, I have to specify `schedulerName: stork` in the specs of the Pod/StatefulSet (see [docs of piraeus](https://piraeus.io/site/docs/optional-components/#scheduler-components)). Because the StatefulSet is managed by the operator, I have to specify it somehow else... Is this possible with the operator (and the `CrdbCluster` CRD) or do I have create the StatefulSet "manually" without operator?
