The ability to have an automation trigger an action or actions when a specific field or fields meet the selected criteria. Here is an example:

A document which has two required signatures (client and sales) among other data but most importantly, a field that has a drop down for length of contract terms - 12M, 24M, and 36M. Once the document is digitally signed by both parties, it is moved to a specific folder based on the selection chosen for length of contract terms (e.g. 12M terms gets moved to a folder labeled 12M, etc).
