Sorry to be late to the party, but yeah, I was thinking to do so and there is even an component DualListSelector kind of ready for that in patternfly as you’ve probably already figured through the PR. I’d love to switch all our use-cases to that component, but it’s missing some bits.
I was digging into it already, but it was my early react days, now I have far better idea what needs to be done and even some code ready, I can try to help with implementation, do not hesitate to ping me if you’re unsure
