How would I add a drag bit to the bit section?
I use a diamond drag bit with V-Carve and either UGS or Picsender. The key is to make sure your carve makes almost no Z height changes for the carve.
In easel with an X-Carve, you could set the DOC to the amount of pressure you want on the bit for your material, and make sure to turn off the spindle. As long as you don’t exceed the maximum DOC per pass for whatever bit you choose (preferably a v bit with a pointed tip) you should be ok.
