# Can I Specify who the Help Action helps? [duplicate]

Let's say my party is attacking a dragon. I'm a Mastermind rogue who can use Master of Tactics to use the Help action as a bonus action if I'm within 30' of the dragon. Can I specify who in my party I'm giving the help to? Or will it necessarily be the next player who attacks the dragon?

Let's say the paladin in my party has his turn next and he decides to attack the dragon... but I'd really like to give advantage to the other rogue in my party who goes after the paladin. Can I specify that I'm helping the rogue?

If so, how would this be role-played to make some kind of logical sense? How would it play out?
