Partial delete of URLs

When I press and hold or swipe backspace to delete a word, currently it deletes an entire URL all at once. I’d like to see an option similar to swiftkey where when a "word" has both letters/number AND punctuation, holding backspace only deletes to the closest punctuation mark in the word.

It would make copy and pasting urls, particularly ones with very long tracking codes, much faster and easier. YouTube for instance adds a tracking code at the end of every link copied from the app, and being able to hold backspace to delete the part of the URL that begins with "?=" rather than the entire link would make it much faster and easier than having to either repeatedly tap backspace to delete a long string, or having to precision highlight the part that needs deleting.
