Ability To Flag Accounts - UBS, STS, FMS, BPS

Initially seeking to not close/terminate an account but to freeze from any transactions by users without consulting management. Thought that idea through to be problematic but think if the warning note feature was much more conspicuous such as flashing screen size when an account is accessed by a user. This enhancement would function using the Cash drawer, STS, UBS and FMS. The current warning note is just too small and not noticed by front line users.
