I don’t think that using the setup software will help you out.
Although I don’t really understand your problem. You should not get prompted to select a user until after you choose a device, in which case you already know what device you are connecting to.
There is not a way to change the default Admin name on the EX4, and I imagine that if it is not apparent there probably is not a way on the EX2 either.
If you want to use another use though, just create a new user and name it whatever you would like. Then create a cloud account with the new user.
If you have any Private shares, give the user access to them. This will give you the same access as the Admin accound, but with a custom name.
