"Risk %" box beside the “Quant” box

Dear Mr. MatthewKlein,

Can you add a “Risk %” box beside the “Quant” box on the C2 quick trade?

What I am looking for is an automatically calculate volume per position based on risk % of the account balance tool, when we have entry/exit price.

Please look at this link for more infomation: Position size calculation

Thank you in advance.
