Bootleg? And no, you have to find them for your character, but typically certain lows like Kasumi's 1K and her PP2K cause the opponent to fall back in a way where you can force the opponent up when used from a launch or after a bound, and attacks that have the knockback like her 66PK or 6P(done twice in stun) cause the knockback too, then you just use whatever move you can to tech them up
