Take your pick from the "latest" ~2009 IPFIX Information Elements:

https://www.iana.org/assignments/ipfix/ipfix.xhtml

One can stuff almost anything in there.

Now if one should, and if one is allowed to.....

There is a reason why the marketing companies that control the general Internet moved the browser to HTTPS and are 
trying to move to using their VPNs/CDNs: cannot modify the data to alter or remove the Ad in-flight, and cannot easily
