Pausing automation
Set the case status to Blocked in Case Management to pause ADMS automation for this dependency. ADMS will skip updating it in the manifest while its case is Blocked — other dependencies in this PR (or future PRs) are unaffected. ADMS never changes a Blocked case's status automatically; move it back to Open (or another active status) yourself when you're ready to resume. See the case link in the table above.
