'Success By' rolls

Hi, I'm wondering (and if I've missed it somewhere on the wiki, feel free to kick me in that direction), if it is possible given the current roll20 system to roll a dice (say, 1d100<35), and have it not only list whether the roll was a success, but also the number it succeeded by? So, if I roll 1d100, with a target of 'below or equal to 35', and I rolled a 20, is there anyway way to make the system record that the roll was 15 below the target? For reference, I'm a Supporter, so I don't have access to the API.

At this time there is no success by X amount system although it is a commonly requested feature. Sorry. Perhaps it will be considered the next time the Dice Roller is worked on. :) - Gauss

Thanks for the reply! I did some pottering around, and I discovered that there's a way of approximating that feature by rolling 1d100-x, where x is the target number. The result ends up being either a negative number (which is a success) or a positive number (which is a failure) Just in case anyone else is looking for some way of working around that.
