Eligible for Nation and Years to Gain Nationality Issues

[CaptainSa]

So in an effort to see some more dynamic international action, I've been looking at trying to make it easier for players to change their nationality and represent different international teams, but I'm running into some issues:

1. I set every nation's years to gain nationality to zero, but this had no effect, and the default requirements remained. Setting this to 1 did change the number of years to just 1. I was wondering if there was a way to change this further?

2. There's no option to change the number of years to gain eligibility (or get rid of these requirements completely) in the default database. Is there a way to do this in perhaps the rules editor? Or is there any way to do this at all?
