Multiboxing Vehicles

Has anyone been able to create an "enter vehicle macro"?

I have an X-52 rocket on a master. I'd like to have my slave enter the vehicle using a macro, but I haven't been able to come up with a working macro to do this.

Some exit vehicle macros are out there on this site and google, but none that can /target master and enter vehicles.

Basically, I'd like to avoid having to alt tab to slaves to enter the X-52 (and mammoth in the future)

Thanks

/assist
hit your Interact with Target key (two key presses)

That's how I do anything with vehicles. With ISBoxer, your IWT key automatically /assists and IWT if you have it in the right key bind group.
