Anyone using Rithmic Trader Pro for options

wondering if anyone out there is using R Trader Pro (Rithmic trader Pro). I mainly am looking at futures options (in addition to other things like trading outrights/spreads)

Does anyone here know how to get the greeks by calculating in excel - i heard JW (the founder) mention that

Can you trade option spreads like verticals? and is it easy to roll option positions?

Is there anyway to see volatility of an instrument either in a study or as a column?

anyone actively using it would appreciate a response or a message
thanks
