Just wanted to report, I decided to do some experimentation by setting the oscillators to a really low frequency so that I could better understand what's happening and apparently, though you can't sync more than one oscillator to another directly, you can daisy chain additional oscillators in order to apparently indirectly sync the oscillator.
What exactly I mean is that I'll have, for example, three oscillators connected and I want osc 2 and 3 to sync to osc 1. I sync osc 2 to osc 1 but then I sync osc 3 to osc 2 and I according to an analysis I did with a waterfall spectrum meter, apparently this does end up forcing osc 3 to sync with oscillator 2 which will make it also sync to oscillator 1 and so all 3 oscillators are synced.
I haven't tried daisy chaining more oscillators but I assume it would work. Most importantly though, unless I am mistaken, this does give the user a workaround for Modular V's one oscillator sync per oscillator limitation.
I am including 2 images:
In the first image, if you hold up a ruler, you'll clearly see that at -33s, -25s, -17s, -9s, and -1s the waveforms that are at otherwise very different frequencies line up.
In the second image, in case anyone is curious, I included a screencap of the patch I used for this experiment.
