Yes, I have a separate banding unit. This link will show the original setup I wired and taped together. It did a great job, though I have made some improvements since. Keep in mind, this is wet tall fescue sod I am drilling into.

 Actually, here it is again. Your drill is of course different, but openers can do a lot of side soil movement without inverting or disturbing it. You can also put a corn planter closer wheel system on the back of the disk or knife used for mid row banding if you need it closed separatly.
