We are planning on using Projects for assembly order projects that have common tasks, so I would like to set up templates. However, I have not found a way to scale the length of all tasks by the amount of items that needs assembly.

For example, if Widget A has 10 tasks that take 5 minutes each, and we have 5 Widget As to make, how would we expand the time or quantity of tasks in the template to accommodate assembling the 5 units? 

If there's a different or better way to do this, please suggest! I appreciate any thoughts on solving the scalability need for templates. Thank you in advance.
