Default-information originate for OSPFv3

Hey folks, For injecting a default route into OSPFv3 normal area, we don't have default-information originate command in FRR. Wanted to check if this is achieved differently or if there is a patch available somewhere. Looking for functionalitysimilar to what we have in OSPF default-information originate [<always|metric (0-16777214)|metric-type (1-2)|route-map WORD>] Thanks -- Sonum
