Is-boxer Gathering solution?

Hello guys asking here for bit of help

So far I have it setup so that when I push a button (then all of my toons are getting same camera angle and mouse position, for easy gathering)(just like Mirai-youtube video "Multiboxing - World of Warcraft Gathering")
what I would like to have on same button is my toons moving forward so that I can be certain when flying that my toons are on the ground when farming.
Are there a solution to this in the steps in key maps, tried many things just not been able to find the solution.

kindly regards
