JMeter http request DELETE with body

I have proprietary http based API to test from JMeter. Unfortunately some of the endpoints of the API are expecting http DELETE method with a request body (I know its questionable API design to use DELETE with request body, but I have no ability to change that API and need to test it).

How can I test it from JMeter? It seems that standard HttpRequest sampler silently ignores my body payload without any warnings. (When I try it in POSTMAN its sending a request body for DELETE method)

I did find an old JMeter plugin called HTTP Raw Request that somewhat helps but still doesn't auto-calculate "Content-Length:" http header for my body payload...so I have to do it manually for every test case - which is a pain for dynamically generated data payloads.

So my question still remains: How can I test HTTP DELETE with request body from JMeter?
