A quick fix for simplified nested interpolated string?

[Flithor]

original code:

var str1 = "the strings";
var str2 = $"abcd{variable}efg";
var str = $"{str1},{str2}";

Now we can quick fix it to
↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓

var str = $"{"the strings"},{$"abcd{variable}efg"}";

but we cannot quick fix it to
↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓

var str = $"the strings,abcd{variable}efg";

Could you add a quick fix to simplify interpolated string that include const string or other interpolated string?

Or in other words: "Merge constant strings in interpolated string"

It would probably make sense for inline temp to always do this with strings by default.

"Merge constant strings into interpolated string" is optional.
