I do not see a way to add a whitelist of IPs using an annotation. Is this a planned feature?

Something like nginx.org/whitelist-source-range followed by a list of comma-separated IPs? This would be very useful and I have yet to find a way to do it using this ingress.

If this isn't a planned feature, is there a way to do this manually? Would that involve writing a custom annotation and restarting my ingress?
