That's not a problem. By definition, successful steganography
is undetectable even when you know where to look. Otherwise the
steaganography has failed.
Encryption is successful if the attacker can't find information about the
plaintext without the key. Ideally, he can't answer questions about the
plaintext any better with access to the ciphertext than without.
Steganography is successful if the attacker can't distinguish
message-holding data from ordinary data without the key. Ideally, he
can't guess whether a message is present any better upon inspecting the
cover data than he could without being able to see it.
With this model there is no problem in making everyone aware of where to
look for cover traffic with stego data in it.
