The only real issue with using sanding sealer is that it sometimes doesn't stick well to finishes. There's a soap-like lubricant added to make it sand easier and not load up the sandpaper as quickly. It's that lubricant that occasionally interferes.
Personally, I have used sanding sealer under shellac, lacquer, and poly, and haven't had a problem yet. That's not to say that you won't, just that I haven't... yet.
So... if you're worried about even the possibility, what can you do about it? Use a coat of shellac. Shellac is one of those odd finishes that sticks to EVERYTHING. I'm confident that if you laid out the sanding sealer like you wanted, smoothed it out, then laid on a coat of shellac, whatever top coat you use will stick great.
