Automatic Debt Reminders

Is it possible to change the time automatic debt reminders are sent from CAS360?

The issue I am coming across is the reminders are sent out around 3-4am in the morning and we are then receiving new invoices with additional late fees around 9am in the morning meaning our clients are receiving confusing information and as a result are only paying the amount noted on the first email which isn’t always correct.

I would like to change the time auto reminders are sent to around midday once the debt alerts have been updated from ASIC.
