When creating a schedule for non- user employees, we want it to be based per tasks of the corresponding project. 
The schedule in planning has all the features we need to create and view the perfect schedule, except that I cannot find how to limit scheduling to the specific tasks of a project, or to only such items that are on the sale order of this project. 
Another issue that I cannot create a pipeline there with upcoming things to schedule unless they are scheduled right then. The only way to do that is in project, 
but project has 2 issues: 
1. it does not allow scheduling except to a user, and we did not want to pay for users for all employees, 
2. It does not have all the good planning features.
Can somebody advise how we can have these in planning: A. Pipeline of upcoming unscheduled items (also a way to indicate priority would not be bad) B. Limit to project tasks?
