Bi-weekly frequency date/time expression
CSM/CAM Version : CSM 9.40a

We have an automation process one-step that automatically generate tasks on various frequencies set by users in their work orders (facilities) This was created by a Cherwell partner before I started and I received a request to add bi-weekly frequency to the options. There's currently daily, weekly, monthly, quarterly, available and I'm having a hard time wrapping my head around the date math in creating a bi-weekly frequency expression.

Below I'm going to post how the weekly frequency is setup and maybe this can be copied and modified to bi-weekly?

Weekly expression:

Custom Expression listed under "Value:" which is a user selected date for when they want the process to start

The modifier here seems like the main factor that makes it weekly

any suggestions would be appreciated, thanks in advance!
