### isolate users in a project

Hi,

Is it possible to isolate users in a project without modifying the policies?

What i want is that every user has control only to the instance he created.

I messed around with policies and create a role owner and assigned the role in policies to be able to do what a user can do now in a project (delete,create,reboot etc instances, create/delete routers, networks etc).

Now i want the users who;s role is user or member to be able to modify only the instaces that they created with userid!

Is there a simpler way to do this or i have to modify all policies for thsi to work?

Thank you!
