I have an example where I have a service contract with two service lines of type invoice plan.  My Periodic invoicing is prior invoicing for the year.  I.E. 7/1/2022 - 6/30/2023.  

My service line 1 has a valid from date from of 7/8/2022

My Service Line 2 has a valid date from date of 7/15/2022

When I invoice these 2 lines for the first year IFS will prorate the invoice lines because they were not valid for the entire invoicing period.  The IFS customer does not want these prorated and billed at full amount and the end date to be adjusted for a 1 year term based on the valid from date.  So line 1 should generate for 7/8/2022 - 7/7/2023 and line 2 should generate for 7/15/2022 - 7/14/2023.

Any ideas?  I don’t think IFS will do this natively, wondering if anyone has some ideas?
