How can I set a custom field date one week *before* another custom field date?

Question

All I seem to be finding in automation settings/rules are either forward or dependent on today's date.  I want to be able to set a date one week before another date.

If it matters, I'd like to set a rule that automatically sets one custom field one week before another.  But, I'd also like to create a button that sets the due date to one week before a custom field.

Thank you!

I just want to confirm that there isn't a way then to set a custom field date one week before another custom field date?  I can do it in relation to the card due date, but not in relation to another custom field date?

Try:

{cardduedate-7d}

Thank you for the response.  What am I doing wrong?  The Production Deadline custom field remains blank.
