That’s not possible today. If you’d like to submit a request for enhancement, please raise an Issue at Issues · tigera/operator · GitHub, explaining clearly your use-case (i.e. why this is useful). And if you’re able, a PR to implement the feature would be even better.

As you can imagine, there are more requests for features than resource available to implement them. Features get prioritised according to community demand, so raising an issue provides a place for people to indicate their support for a feature request.
