Is it possible to get consolidated status report for the complete test suite collection with the custom values
Can you give us more details regarding the products and versions you are using? Also- what is the application/testing use case?
Consolidated status report is possible based on the below higlighted email setting. But you should have Katalon Enterprise License, to enable this option.
Below is the sample screenshot of TestSuite Collection Email.
I guess you cannot print custom values in email reports.
Please read the below for further details.
