Yes... Use G29 P1 U T That will start probing the bed with the points as far away from previously probed points as possible.
When you have 8 or 12 points.. It usually makes sense to stop the probing and do the physical adjustment of the bed.
And then do the command again until you have the bed as physically level as you can get it. At that point you can do a G29 P1 (with or without the U option) and probe to completion to generate your initial mesh.
