Ability to set a desired completion time for a PM so we can sort based on overdue PMs.

We would like to set up our PMs with designated completion time ranges. We have a lot of quarterly PMs that need to be completed within the first month of the quarter or semi-annual or annual PMs that need to be completed within the first month of the period. Can you please create a column in the PM tab that has options for: 1 week, 2 weeks, 30 days, 45 days, 60 days, 90 days?
