How to identify a project cost accounting string specific to the cost (and not the offset clearing)

Summary:

We have reports that we have built to report project costs and to report that project costs "cost" accounting string. I am trying to identify a more effective method to identify the "raw cost" accounting line vs the clearing line, since the actual expense line is not always categorized as "Raw Cost".

Content (required):

For example, if you look at the transaction below, you can see that we have a project cost transaction - this transaction has two associated accounting string lines. What I want to always report is the line that is the actual cost line with respect to the accounting, and not the "offset/clearing" line.
