Multiline String in Tree mode

Just went through the options and I could not see any for "supporting" multiline JSON string. (Yes, I am aware there is no such a thing in JSON spec however, I believe a JSON editor could make the experience less techy)
Is there trick I can do to make the experience of writing a multiline string a bit more pleasant?
The idea is that when editing JSON string newlines are interpreted as such then under the hood the actual JSON being edited contains the \n and \t for tabs and so on.
