Default permalink -1

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” at the end of 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
