With all our sandbox and prod accounts annoyingly existing in the same place, is there anyway to go directly to a sandbox instead of being rerouted the prod every time? If you are so kind to respond, if you could please start a thread so that I can be notified, I would greatly appreciate it. Thanks!

hover over roles and go to "view all roles". Then tick the default role checkbox for your Sandbox role.

If you use a direct link like

<https://system.na2.netsuite.com/app/login/secure/enterpriselogin.nl?c=XXX>

, replacing the X's with your account number it will log you directly into that account
