Minecraft banner?

Can you put a banner on the back and on a sign in the Minecraft Bedrock version? If yes how?

On the back?

The sign is simply in the anvil

The only way to get on the back is with mods

No, unfortunately not at the moment. Unfortunately, the Bedrock is left far too far behind and is rather neglected by the developers. She does get the updates, but bugs are often still there.

Yeah, like a pillager guy

Tried that with the anvil, it didn't work

Unfortunately, that doesn't work with the Bedrock.
