Partitions

So F5 has no way to make user x to access some sources and user y access same and some other sources only since I can not use multiple partition on a user.

Then How i suppose to migrate from netscaler with this problem. Cause on netscaler side I can able to do this for our devs to access only specific stuff that only allow them to use. Yes with a little customization but it works. But since i do my research could not find a way on F5 side?
