HP Bars on Monsters when party member attacks mob

[Dragonis1701]

Similar but not quite the same as:

Is it possible to have the HP bar of a monster display to a party member when one person in the party attacks a mob and update the bar as the mob takes damage? Currently it only updates if the party member also damages the mob but I would like it to update in real-time as the mob is being damaged, for all players in the attacking player's party.

Having it so that it shows the monster's HP bar to all players that see the mob could work, too, but the reason I want to add these players to the damage log, is so that the hp bar updates when the mob takes damage/is healed. This way it's more fluid looking instead of just showing the HP bar but the bar does not change regardless on if the mob takes damage or not.
