It would be good to have “application/merge-patch+json” as an option in header.
Right now i need to copy and paste it or type it manually every time I change something in the body as the header defaults back to application/json.
you can set the headers programaticaly in the test script, or use a variable for it
I could, but it would be really convenient to have it in the drop down or smoehow save a custom header value like content-type : application/merge-patch+json, so i can use it multiple times easily
if i have to do more than two api calls in a project, i just make a generic parametrized object and reuse it across testcases 
or,if you like it the old fashion,with tones of objects in repository, you can simply copy paste objects to duplicate them and just change what is needed (url, body)
