Be able to create a custom value that is the result of a calculation of any other custom value, platform value, or field.

Example: creating a custom value for one year from the current year. Such as, {{right_now.year}} + 1 year. If {{right_now.year}} returns 2024. This proposed functionality would allow the creation of a custom field that recognizes {{right_now.year}} as a date value with a format of year, and then allow the calculation of any additional date value to it - such as 1 year, which would return "2025".

This would greatly facilitate manual entry of year in drip and nurture sequences that occur in October, Novermber, December time periods. It would allow for user admin customizeable custom values for any number, date, or monetary value held by the system - whether in platform held values (such as {{right_now.year}}) or in other custom values. This proposed functionality would greatly expand the capability of the custom values functionality for admins and users and its applications across emails, sms, and funnel/site pages.
