Rawhide whips are really very stiff, and a bit lighter than leather whips. You'll have to work it out even more than a regular leather whip, to get it broken in. When the whip is looser, you can make many other moves with it.
I used to do the following on my Mexican bullwhips (which were of a better quality than those swivel handled ones which abound on the Internet, but are now extinct
) but I DO NOT RECOMMEND IT (it worked for me, and the whips are fine). I used to soak the thong (not the handle nor the knots) in Armor All, and the next day it would be very flexible, never getting stiff again (for some reason I dislike the sound of that word... LOL!)
Later, I would just keep it conditioned with leather dressing.
Rawhide is much tougher than leather, so it will stand much more abuse than the second one.
Of course, getting back to your question... you should be able to do all the cracks with such a whip, IF AND ONLY IF, it has a good construction. My whips used to be made with a steel rod and a tapering piece of rawhide as a transition. These whips usually taper very rapidly and a few inches after the transition, the rest of the thong remains straight. The fall adds a little taper, plus the cracker, but that's it. Usually you'll have to cast or cut the whip with much muscle to get an "easier" crack.
If the whip has a good shape, i.e. even taper, and good weight distribution, perhaps even balance (you can't expect much from most rawhide whips), it will be easier to perform all the basic and complex cracks. If it has good shape and does not let you do them, perhaps it only needs to be used more to allow the thong to travel the way it should for each crack.
Just a thought.
