Add ability to macro Ride Pinion

[Catwho]

Love the whale, riding it right now in Bozja doing some low key farming with friends.

But there are some annoyances with it. Since I play with keyboard primarily, I have to grab to my mouse to right click the mount, be within range (which is smaller than it looks), and zip through the menu a few times to get to it.

Can we please have a text command for /ridepillion <seat.4> or some means of indicating what seat? Or also /ridepillion <firstopen> to grab the first numerically open seat.

Then I could put it in a macro command on my keyboard and not have to deal with grabbing the mouse or controller.
