I thought I’d clarify why there’s a need for such feature. The problem with deleting are URLs that are not sorted out, let’s say we have:
Post name tomato https://site.com/post-name-tomato
and then appears the duplicate
Post name tomato https://site.com/post-name-tomato-2
If we delete the older file which in my case is always way to go we’re left with
Post name tomato https://site.com/post-name-tomato-2
The “-2” at the end of URL is not fixed/removed
So one idea to solve this would be to remove all the duplicates AND original files at one click an then re-import the new ones. But if there was a feature “keep new file but fix it’s URL removing -2,-3,-4 etc.” that would be even cooler…
