Add d6 to d100 roll before calculating CS/CF?

Is it possible to add a dice roll to a 1d100 roll before calculating the total for critsuccess and critfailure? Been banging my head against this for a week.

I don't want the d6 roll to have a cs or cf, just the total of the 2 rolls.

example:   [[{1d6+1d100}cs>50cf>49]]    4+49=53cs

cs/cf doesn't currently work when combining rolls. ie inline roll [[1d6+1d100]] 

however, the inline roll seems to work for setting cs and cf, maybe you can adjust your cs and cf points using your 1d6 modifier roll.  

[[ 1d100cs>[[50-1d6]]cf<[[49+1d6]] ]]
