Here is an alternative suggestion then (still not perfect, but certainly fewer clicks).

I have a hotbar (shared across all jobs) for stuff that I use on rare occasions. Gearsets for DoL jobs, "Dig" for maps, Chocobo summoning / dismissal, stuff like that.
I have a second shared hotbar that has two macros on it. One macro shows the previously-mentioned hotbar, one hides it.

If you wanted, you could setup something similar, so you could readily access and drag over the duty action from a separate hotbar as needed.

It's certainly not perfect, but I don't believe there is a command you can put in a macro to execute the duty action. If there is, I would be very pleased to know about it.
