Is there feature to ignore line types w/in payables invoice being considered in OPM Actual Cost??

Is there a feature to ignore certain line types within a payables invoice from being considered in OPM Actual Cost Process?

We would like to run OPM Actual Cost Process (Period Moving Average Cost) and we would like to be able to exclude the VAT (pass through tax) line type that is part of AP Invoice from being included in the Actual Cost calculation. Is there a feature that would allow us to ignore this line type?
