I suspect it's actually buried in the code, as I've gone over the talent in Data Editor view and can't find a way of doing it, but if anyone has already done something similar, it would be great. (I'll check the XML for Signature Vehicle as soon as I get home, too - there may be a way of doing it there).
Well you have a couple of options. You could manually edit the vehicle in question using the data editor but then you're going to have inaccurate info for other silhouette based stuff. Likely your best bet is to just GM grant yourself a rank of Larger Project. Of course, as others have pointing out, things are working as intended, so you'll of course want to run such a thing by your GM.
