While creating a new Template (Marked as Draft) users can not "Stitch" insert a Task Group from another template if it is also marked DRAFT, only if it is Active template
Once a new Task Group is created in say a Draft Template, Users are not able to insert / clone that into another Draft Template. That means if that new Task Group is going to be reused in multiple templates, Users have to rebuild exactly the same in all other templates to use it. Stitching and cloning can work with Active Templates, which it should not. It also works for adding into other Projects. But does not seem to work for Draft Templates.
Reduce the effort for reproducing identical Task Groups to be used across multiple Templates being developed in Draft status. Will save a lot of time and reduce errors from manually re-creating.
