RestClient request body

In the rest client when you chose request body -text and past there some json or xml formatted text, then the format is lost. And it looks like a simple one line string. 

Is it possible not to lose format? For very long request bodies it is very unconvinien

example:

this

<?xml version="1.0" encoding="UTF-8"?>
<xmltest>
   <apiKey>test</apiKey>
   <modelName>test</modelName>
   <calledMethod>test</calledMethod>
</xmltest>

after paste it become this:

<?xml version="1.0" encoding="utf-8"?><xmltest><apiKey>test</apiKey><modelName>test</modelName><calledMethod>test</calledMethod></xmltest>
