Nope, I have found sitting on the ground with me elbows rested on my knees, which are bent up, works great. Best part is my legs are coming with me, so no need for extra gear

. If the ground cover (ie grasses) are to high I will kneel and do the same thing on my opposite shouldering side. If still no good, then I shoot off hand but limit myself to the range. I do however spend the bulk of my range time shooting all three ways, so I am really not accustom to a traditional style rest.
