Use Jira built-in statuses instead of "Epic Status" custom field

This is very confusing... and annoying.

All workflows has:

• To Do
• In Progress
• Done

Sometimes instead of "To Do" is old Open and in place of Done is Closed...

So now you have a status categories so maybe it might be a good idea to choose a responding status from those lists.
Or maybe force projects which has Epics to have those statuses (To Do, In Progress, Done).

There is also

statusCategory

which migh be a good use here.
