I have a large project with multiple test suites each of which contain multiple test cases. Many of the test cases contain endpoints that require similar headers (about 15 headers that require lots of manual typing to enter).
I see there is a button to import headers (highlighted in red), but I don't see any export options.
Is there a feature where you can copy and paste the headers rather than needing to re-type the headers each time?

Select (click) the header name in another request and use Ctrl+C, this should copy the header from another request. To paste the header use the button paste from clipboard.
