Is it possible to set the compression type at request level?

Is it possible to set this for a single request only? im in a scenario where a single test step out of 14 needs to have this compression set to gzip to pass (and if its on the other 13 will fail).

I have tried setting it to none and then applying the folowing headers:

Content-Encoding: gzip
Accept-Encoding: gzip,deflate

however this doesn't  work.

Thanks
