I have a custom module with payment terms lines. The payment terms lines have 'Due Date' field (date type) with 3 maximum lines. The Due Date is progressive by rule i.e the Due Date of the second line is greater than that of the first line, and that of third line is greater than the second line. Meaning Due Dates cannot be same. The requirement is to continue to show sticky window notification few days (say 5 days) to the Due Date of the line and subsequently second line and third line. The notification should show only when the user logs in and loads the affected module in list view. I have considered several activity reminder modules, but they seems not to satisfy this requirement. What approach can I use to achieve this?

Appreciation in advance.
