You have lost me, its a stencil, you can change the aperture size, you can change the thickness and you can change the walls of the aperture. And all of those things will be in the papers anyone can find with a google. I have no clue what safe air g

Machines don't have any kinda of local correction on specific offset on PCB, you can only edit main board and it will reflect on all other offsets in panel. For some high running projects we merged 2 pick and places into one (for example 0 degree rot
