Once a project is created, there is no current way to refresh checklists in the new project. Either
a) refresh the checklist from within the project
b) when duplicating a project be prompted to import new/updated checklists
I have spent time building projects to share with my team, only to realize that a checklist needed to be updated and there is no current way to get the revised checklist in the project so a brand new project has to be created. A BIG time sink.
