How do you group invite without targetting?

[redhorse]

On live, eventually a quality of life change was made where you can just /invite player name from anywhere and they will get the group invite. After being on p99 for so long this took me quite a bit of time to get used to when I started playing on progression servers. All that said, this feature is intentionally disabled on p99, as it did not exist on live during the scope of the p99 project timeline. Sort of like the map, for example.
