Passenger Grab Handle – has anyone extended it?

My kid wants to ride shotgun (I have a XP 1000 2-seater) but can’t reach the grab handle unless he leans forward. Kinda defeats the purpose of the harness I’m installing if his back is not against the seat. Has anyone built or seen an extension for the passenger grab handle so it can be reached with shorter arms? Maybe other Polaris vehicles have longer grab handles that I can swap out?
