Allow selecting multiple quotes in a row to merge them

[JakubKoralewski]

The first one on it's own doesn't make much sense.

But if you could select both it would be great. Make the format then I Thor 67:11-15 but also make sure that if the first would be something like I Thor 67:59 then merged with the next it would have to be either: I Thor 67:59-15 or I Thor 67:59-68:15. Or third option is just don't change the formatting and stick with the first one.
