Butler: Move Due date by Custom Field Value Days?

[Irakli Chkhetiani]

SETUP:
1. List RECURRING contains tasks that repeat after some time.
2. List ACTIONS contains tasks that currently can be done.

PROBLEM:
I want cards in the RECURRING list to copy in ACTIONS when they're due in one day or less, and the due date of the card in the RECURRING to move by {custom field value} days.

MY "SOLUTION":
I have seen some scripts that use custom field value, but all Butler Gives me is their custom interface. I haven't found a way to write scripts by hand.
The closest I have come to the solution is to add buttons for each NUMBER of DAYS and click the button manually.
