Need advice on how to target dead players in stacked fights

Tumster

I really noticed the issue in the vSS dragon fights, usually the dps/heals are stacked tightly in one or two piles but inevitably one will die. It is, of course, the fellow dpsers job to revive him. I find it next to impossible to target a deadbody among a pile of live players to get the illusive "F" option to revive. So a whole lot of time is wasted, sometimes by multiple players to revive a single dead comrade. Discord is frequently filled with chatter of "can't target his body" "can't find the deadbody". Is there any easy way to target a deadbody, among a pile of live adds or players, for ressurection?
