I want to create a list tied to a specific form.  I need to filter the contents of the list to a value on a workflow variable only.  The variable is named "status" and the value I want to see records on is "rejected".  So far, I have tried the following in the list filters with no joy:

e.customProperties.variable.status='rejected'

Looking at the actual data tabled, I have one record that matches.  The above produces no results.

TIA,
