Payment terms - end of month after 45 days from invoice date

I'm looking for a solution to a payment term issue, please.

Calculate 45 days from invoice date then return a due date of end of month from the added 45 days.

For example.  Invoice date is 01/09/17 45 days from this date is 15/10/17 so due date should be 31/10/17

Example 2   Invoice date is 17/09/17  45 days from this date is  01/11/17 so due date should be 31/11/17

Is this possible using advance payment terms?

Thanks in advance
