I am working on scheduling a project and am not exactly sure on the dates of each task yet.  I have broken the project into many small tasks.  I have an estimate on how long each task will take. 

Since the tasks are controlled by the project deadline, I want to be able to assign a quantity of resource types (like: programmer) rather than assigning names.  I want to do this without overscheduling a resource by naming it too many times.
