Update Retainage Release notification

When Retainage is released, Triemble Pay automatically emails the subcontractor and states "Retainage has been released, please log in to submit your payment". This waste everyones time as the sub then logs onto Triemble Pay only to find out they cant bill the retainage untill the billing period is open. That automatic email needs to be updated to state "Retainage has been released, you can now bill the retainage during the normal billing cycle 11th through the 20th. Reminder, you will not be able to process the retainage untill you also upload the closing documents".
