yes it's possible. Alex said he doesn't recommend doing over 8 though because of amount of VRAM etc required to run said animations but I think with the improved memory/power consumption of vs4.0 that it shouldn't be too much of an issue.
here are the angles:
4 = 90
8 = 45
12 = 30
16 = 22.5 (not possible, because only integer values can be entered so use 22 or 23)
24 = 15 (better than entering incorrect values)
32 = 11.25 (also not possible to enter, round off to 10)
360 = 1
