Suggestion for Addons using WBS rather than LMSEO totals

Sage Estimating, especially when used for Engineer's Estimates, where the Engineer models the various subcontractors as LMSEO COSTS rather than purely Sub PRICES, the need to mark them up properly has been, in my opinion, something Sage Estimating has not done as well as other programs specifically designed to accommodate this usage.  I have included a screen shot of what this could look like, if, rather than starting with the direct LMSEO COSTS in the Totals page, we could select one WBS and receive the LMSEO direct costs in separate columns (and I suppose the hours for both labor and equipment should be included).  The screen shot shows the current Totals cost summary, what a WBS summary would look like, as well as a WBS summary with addons, to illustrate how it could be used.

One advantage is the ability to see, if structured as shown, each Subcontractor's PRICE to the Prime contractor.  Another advantage is that Contingencies, Escalations, and Prime Markups could be applied at different rates depending on the WBS value used.

Please let me know if you think this would add value.  I believe it would make Sage Estimating more useful for specific estimating approaches, such as Engineer's Estimates, as shown in the screen shot example ....
