Calculating Material Costs

[Ziyad Yehia]

Hi there TJ Team,

First of all thank you for all the effort put into making this software. I'm new to it, but so far I think it is amazing.

I have a question about calculating material costs. On ProjectLibre, for example, it is possible to set per-use costs for certain material resources. 

For example, one may say that a jar costs £1.00, and for a particular task, I allocate 5 jars. Therefore, the total material cost for that task is 5 * £1.00 = £5.00.

I understand that, at the moment, we can do a "charge 5" property, but I like to be able to define the unit cost at the resource level, and allocate a certain number of units to a task.

Is it possible to do this in TJ?

Many thanks in advance

Ziyad
