Issues with youth intake nationality

[Venator77]

I've been editing a Yugoslavia database to use in a new career save but I have a major problem. All of the clubs were set to Yugoslavia as the nation they are based in, but they still produce youth intakes under the current nations they are in, ie Dinamo Zagreb producing Croatian players. I don't want this as I want all the clubs to produce Yugoslavian players. What do I need to do?

Here's the file I have been editing attached to the post.

Thanks for any possible help.

I figured it out. It's just a matter of moving all of the cities from the Yugoslav successor states into Yugoslavia itself. It'll be a little tedious moving all of those cities, towns, etc, but it is the best fix I discovered.
