Critical Success on combined number?

I use 2d10 instead of 1d20 in my 3.5-ish game and would like to be able to have e.g. [[2d10cs>18]] work on the total of 2d10, not on the individual dice. (So that if someone attacks with a scimitar and rolls two nines, it would display as a critical hit, just as it would using 1d20 if they were to roll 18.) I thought that [[[[2d10]]cs>19]] or [[{1d10 + 1d10}cs>10]] might work, but they don't. Is there a way to do this currently? If not, could making cs and cf work on Roll Groups be added as a feature?

Hi, apparently this is not possible without using the API. I tried something like this for my own character sheet, but ultimately resigned and wrote an API script that checks rolls for their sum and compares this to a specific number. As an example (untested): on("ready", function() {     on("chat:message", function(msg) {        if(msg.type == "rollresult")        {             var rolldata = JSON.parse(msg.content);             var number = 18;             _.each(rolldata.rolls,function(r){                 if('R' === r.type && 10 === r.sides)                 {                     _.each(r.results, function(roll){                         if (roll.v < number)                         { // Success!                         } else if (roll.v > number)                         { // Failure                         }                     });                 }             });         } }); }); Greetings.
