Hi @Raoul_van_Bergen ,
Since you are on the Business tier, you could create a Portfolio with ALL your projects that have an assignee, due date and effort level (eg. Estimated time). That will essentially create a Universal Workload for you.
You could also ‘automate’ all newly created projects from templates to be added to this Portfolio (as well as other portfolios) via the Project Template’s settings (within the template editor, step 3, scroll to the bottom).
IMO, it is highly unlikely Asana will ever provide an Enterprise feature to a lower tier.
