Payload Conversion on switching Request Type

[AppliedEllipsis]

If you switch the request type from JSON to Custom to URL encoded, it would be nice if the values from the previous option get translated to the new option. If I'm on JSON and switch to custom, I'd like to see a formatted JSON object. If I switch from URL Encoded to Custom, I'd like to see the header splits, etc. If I switch from Custom to another, I'd like it to try to detect and convert the payload to the other formats ( only basic detection, look for encoding blocks, try/catch for json decode, etc)
