Settlement Days [Optional]
ProjMode=p.dd

This only affects cash mode, but you can use it under all settings.
If the amount is paid a number of days after the period ends, you can specify the Settlement Days. The default is that interest (in arrears) is paid on the first day of the period for the previous period, and for rent (in advance) its paid on the first day of the period. Settlement Days allows you to specify a gap between 0 and any number of days after the date it would otherwise be paid.
You specify Settlement Days by adding a 2-digit decimal value to ProjMode. For example:
1 = default, no settlement days, as described above.
1.15 = 15 days delay on the payment (whether the payment is in advance (rent) or arrears (interest)).
