Homegrown Rules Help

Hi everyone, I am creating a database to make Scotland and Canada with improved youth ratings, affiliates between clubs in both divisions etc etc. However, i want to force both the CPL and all SPFL leagues to only sign homegrown players as per a league rule, but also to Canadian clubs to develop and use Scottish players, and likewise Scottish clubs with Canadians, is there any way to do either of these things?

you can try the advice given in this thread But it will effect the whole country https://sortitoutsi.net/content/57776/how-to-force-clubs-to-only-buy-players-from-onea-few-nations

these workarounds will assist you have a play around see what suite your needs run a few sims in game see how the transfer activity goes
