Trailing stop step size

I would like to see a parameter for the step size in trailing stop orders. As far as I can tell from paper trading it is moving continuously (i.e. the step size is the same as the resolution for the price, a fraction of a cent). This is not always desirable. It would be very useful to be able to control by what step the trailing stop moves up. While this can be coded up on the client side, it’s clunky to have to replace orders all the time as an attempt to approximate a larger trailing stop step size and also vulnerable to live communication/disconnection issues.
