What's complicated about it? There are two steps, clearly indicated on their player frame in your party.
1. Retrieve Banner
2. Deliver Banner (or whatever, i can't remember the wording.)
A downed player can ping their own corpse for their team mate, and then once the teammate has retrieved their banner, ping the closest res station. I don't think it's a problem of complication.
Rezzing a player is usually go to body and press button. Pinging stuff and taking banners places? Ain't nobody got time for that.
