Client, TD Ameritrade, currently runs auto-offboarding. Their users all have a line shared across multiple devices(BOT, CSH, DP, etc.). They auto offboard but do not remove the shared line because they also have Lines that are shared across multiple devices with different Users.
They would like the option to remove a shared line ONLY if the line is shared across multiple devices with 1 unique UserID. If the Line is shared across devices, and is associated with more than 1 unique UserID, do not delete the shared line.
