Hi Gary, I see how this would be nice to have, I believe it's on the list, but not a priority at the moment. For now, the only thing I can think of is to use the cost basis and commission cost to solve for the fill price. e.g. fill_price = cost_basis - commission / (number of shares)
I believe one might rather have a list of executions that could be linked, by order ID, back to any one order. Order price could be comprised of many different execution prices depending on market entry style. Knowing true execution price though, for every fill, would give you a better understanding of slippage. Knowing that your order took 10 executions to fill is also useful.
