How can i add issue filter if "contains partial subject of child issue" not "child issue id"
I am using redmine 3.3.3 for project management.
I want to find a parent issue with a sub-heading of the subject of child issues.
The quickest thought that comes to mind is to export your issues to CSV limited to only basic fields aside from subject. Then I bet you'd be able to find your issues using data filters in Excel, Google Sheets or equivalent.
