I want to use Maneuvering Attack to move my mount, and then make an attack action on the creature I move towards. However I want the weapon attack that triggers this combat manoeuvre to be made as a ranged weapon attack against the same opponent, and explicitly with my bonus action prior to the mounts movement. If you need a reason - it's a cool visual for me.
I'm assuming no multi-attack/extra attack or action surge. Just using a straight-forward bonus action and action combination.
When you hit a creature with a weapon attack, you can [...] choose a friendly creature who can see or hear you. That creature can use its reaction to move up to half its speed [...]
I would use Quick Toss:
As a bonus action, you can expend one superiority die and make a ranged attack with a weapon that has the thrown property. You can draw the weapon as part of making this attack. If you hit, add the superiority die to the weapon’s damage roll.
but I am limited to one manoeuvre per attack:
You can use only one maneuver per attack.
Similarly Crossbow Expert is no use, as that bonus action attack is after using the attack action:
When you use the Attack action and attack with a one-handed weapon, you can use a bonus action to attack with a hand crossbow you are holding.
If there's multiple ways, I'll pick the lowest level, then fewest character choices (e.g. fewest multiclassing choices, feat choices, spell choices...)
