Consumable and variable resource

Is it reasonable to try and use material resources for consumables such as boards, pounds of cement/plaster, and how do I use them when a different amount is needed on a different phase or project?
I can only see that creating multiple material resources is possible relating to the different quantities needed. I think I’m missing something

Yes, that’s reasonable. For each task on the project plan, use the “Assigned Resources” section of the task inspector. Add each consumable resource and enter the amount you need in the “Units” column.
