Hello,
There is a difference in the way subtasks are displayed between project types.
If I create a Team Managed project with a Blank template I get a Space that displays Tasks and Subtasks like this:

I've looked into adding the Subtask Summary field, but it doesn't seem to exist in the Company Managed Project fields.
Is there something I can do to make the Company Managed cards look like those from the Team Managed?
