In a nutshell . . . I am quite confident that it CAN be done.
The thing is, VM 2.0.x is still relatively new, so I am not certain if anyone has figured out customization of this element yet.
Have you given it a try?
I DO know that some of the VirtueMart Theme Developers out there have incorporated this kind of tab info navigation into their product page themes. This particular one from YAGENDOO.COM is one of my favorites (thus far).
I’ll look around, myself, a bit more for solutions for this issue . . . it will be good information for others who may want to accomplish something similar.
