Item 0 will have the first byte of the first packet, regardless of what you're actually doing. There's a couple of blocks that do something like this, and they all set the tag propagation policy to 'NONE' (which requires manual propagation), and then get/set tags accordingly. So, if you read the tag from input item 0, and then write one to output item 0, I believe it'll do what you wanted.
