Using a different costing method for estimates

Hello all,

Excuse me if this is a foolish question, I don't have much to do
with the engineering department (or job setup in Vantage) & my boss
wanted this answered. We use average costing for the system-wide
costing method. Is it possible to have job estimates use last cost
(or anything other than average cost) without changing the system's
setting in Module Configuration?

Thank you!
