Create an Access Table that "auto-Populates" with Dates

I need a table that will “auto-populate” with dates (Months) based on some input by the user. The table will have four fields: AutoNumber, PID Number, Month and Year. The user will Select a PID. The PID (Proposal Number) will already exist in another Table. In a Field on a Form, Query… the User will enter a Start Date and Number of months What I need, in the Month Field, is the aforementioned Date plus 1 (the equivalent of one Month) Example: If the User entered January 01, 2017 the first Month record would be 2/1/2017 In the Year field, I need the Equivalent Year of the Month in the same record (i.e. 1/1/17 would be 2017) The User must be able to go back and make changes to the Start date and the number of years. I would assume it would have to back to the table and find and replace the records for the Assigned PID. PID: Z00026A-APCH-NF-1701 Start: 1/1/2017 Number of Months: 60 Record One would be: 1, Z00026A-APCH-NF-1701, 2/1/2017, 2017 Record Two would be: 2, Z00026A-APCH-NF-1701, 3/1/2017, 2017 And so on until there are Sixty records. Need someone who can think outside the Box.
