Can you guys adjust the length of time that the admin keeps a webmaster logged in?

It is so difficult to get anything done when you are in the CCbill admin without getting logged off. It's so annoying! You feel so rushed to get anything done. More times than I can count, I've been trying to get a report, change a form, set up password, etc. Then someone messages me, I chat for a few minutes and then come back to find out I've been logged out.

I know it is for security reasons but can't we stretch the time to 30 minutes or so?
