what happened to party up option

Most of the time I get terrible teammates that get 1-5 kills and a ton of deaths but the few times I do get a great teammate it would be so much more convenient to be able to check a party up option before everyone goes thier separate ways. When I send game invites after they have already started doing something else I think they have to do one too many steps to want to bother joining…idk would just be a nice small but useful addition.
