Estimated Profit Based on Sales and Purchase Quotes

Thanks for the great software.

I know this has been asked before ( View (expected) profit on a sales quote - Manager Forum and was closed, but perhaps it can be done in a similar way to the existing Projects menu. We know Manager is an accounting software, but the functionality is there is currently there to take the sales and purchase invoices to calculate profit, can something similar be done on projects in the quote phase to either determine estimated profit, or, to show profit loss if the quote/project is not accepted? This will eliminate the need of using external software or sheets and can reduce duplpicate work.
