I need to use in my permalinks same titles for different post types and as far as I know the slug must be unique so the permalinks cannot be:
custom-post-type-1/hello-world
custom-post-type-2/hello-world
custom-post-type-3/hello-world
it will be like this:
custom-post-type-1/hello-world
custom-post-type-2/hello-world-2
custom-post-type-3/hello-world-3
how can I add a default -1 to the first permalink so the links will be like this:
custom-post-type-1/hello-world-1
custom-post-type-2/hello-world-2
custom-post-type-3/hello-world-3
U could try one of these

I use them when i want to change my permalink structure, hope this helps u!
