I don't see "blocked date" as an option to pick in the add columns section. In one of the apps that shows blocked work, there is a date shown too, but that app doesn't allow any kind of filtering. Which is why I wanted to use the custom list app to see all blocked work, but custom list doesn't show any "blocked since" or "blocked date" field.
Is there any way I can get both on one app? (blocked since and filtering capabilities)
It doesn't appear that the blocked date is available to the built in custom list.
Blocked date exists as an entry in a sub object to a work item so that's probably how the Blocked Work app is pulling that data.
This might be a job for a custom app. There's some great starting points here: https://docs.ca.com/en-us/ca-agile-central/saas/apps/2.1/doc/#!/example/custom-data-grid
