Change default behavior of Organization / user setting

Hello,

A nice feature would be to have access to change the default behavior when setting up New organizations.

The current default is very restricted. 

I want to change the default setting on new Organizations. I want the setting "Users: can view all org tickets" and Users setting, "Can view tickets from users org" to be possible to set as default. As of now, every organization added requires this manual step to make the ZD portal behave as expected for customers. 

Related suggestion: retroactively bulk change this option safely (ie, without exporting&importing the entire user db!
