Can two OneShot's be strapped together?

[casino66]

Can two Oneshot chassis (PC01) units be connected to make a single two channel chassis?
I have one right now and am thinking of getting a second, but only if I can connect them into one unit rather than having to separate units.
I would mainly use them for a small mobile setup, hence why I want less moving pieces.

I see there are many screw hole openings on the chassis, but am not sure if SCA has an intended way to connect them.

Thanks,
Chris
