Thanks for the reply.
I currently have a CSV that lists out the following in columns.
Country, Job Title, AD Group
These repeat in rows for each group added.
I've done this with every country, basically just repeating the title while adjusting the country and groups to their needs.
I assume I can still use my property patterns to apply those based off the OU selected. Filling out basic information such as office address, zip, etc.
If there is a better way to organize this CSV, let me know.
