Instead of having a 'one size fits all' as in the Global Login Information there needs to be a way of just having logins/password that you can select per device and/or device templates. That way when you setup a new device it looks at the template to determine what login information should be used, or you could just go down into the device setting and pick it.
Having just one Global Login is very restrictive and requires a lot of manual edting when you have different login information for different devices..
Just my $.02
One option is to go to File > Settings > Custom Macros and add your own Global Login and Global password.
