As ZmnSCPxj has pointed out we do have the possibility of adding some information in the onion packet. You can even give every single hop its very specific information in the onion. Say for example you have a node that does currency conversion, you may specify the desired exchange rate in the onion. May I ask what use-case you are looking to implement using this feature?
