Could you do it all the time with charger feat and a mount?
Let me open:
Mounted guy with chsrger feat charges, uses dodge for himself, mount uses dash, rider gets bonus action attack.
That certainly seems in line with the intent of the rules (I don't see why the charger feat would want to prohibit you from the iconic mounted charge), and it doesn't seem OP (you need to invest the GP in a mount, and then also protect that mount in combat, and also probably not be in a dungeon where most mounts find it....rough going), so it's viable. A DM who didn't like that could probably limit you on some technical verbiage, though.
