What should I do to set a unified link for all my collections?

That’s right

This is wrong

What should I do to set a unified link for all my collections?
Or is it just one by one like in the first picture?

I’ve not found anything that says you can set the permailink for all collections via front matter defaults like it looks like you want to do, but I am not that familiar with front matter defaults.
