Limit Order Offsets relative to Bid and Ask

In ChartTrader, there are currently buttons for “Buy (bid/ask)” and “Sell (bid/ask)”.

It would be extremely useful if these buttons could have the option to pre-configure an additional offset in ticks.

For example, I would like to be able to hotkey execute an order to Sell at (bid -n*ticks) which would effectively behave as a aggressive market order, but with a price-cap.
