I think he's done the editor for A, B & C alone because he thought the TI wouldn't need another editor, since it's got the Virus Control. What really puzzles me, though, is the fact that the first developers (let's say Access) does not address this issues and allows for the appearance of such "niche" markets. They're not entirely alone in this. Just check Rekon Audio's web site: they make money selling editors that the synth makers didn't take the time to create in the first place.
There's also that one (from Rekon Audio), but fails to do what you want and, like V commander, it's aimed at the A, B and C only. I also have MidiQuest with the Virus editor in there. But no such feature.
You should also try and post your request on this forum:

I haven't spend much time there, but it seems to me the editors are the result of hobbyists and the forum seems to be active enough (and geek enough, lot's of macgyvers in there for sure)... It's open source, so no royalties but there's already a Virus editor in place and maybe you'd be lucky contacting those who did it. There's been plenty of versions of it (for any model of the Virus, including the TI hanging there), so it's something you should try, I think...
I only noticed I'd might want to do it after I read this XD but if anything turns up, be sure to post here the good news. Cheers
EDIT
checked it again and there's this in the description:
ยท Section Locking.
"Lock any section of the Virus sound engine. For instance, lock Oscillator 1 and Amplitude Envelope. When loading or receiving a new patch, the locked sections will not change. Do you like the effect settings of a patch, or the arpeggiator pattern? Lock them and test any patch with those settings. Forget about random generators."

so I guess that if you lock the edit you made for the soft knobs on one patch, you could load the others without changing that, or something like that...
