I assume you mean a reference point? I rarely use them so I don't know of a way to do it directly, but you can easily place a sketch point coincident with each plane and then create a reference point on the sketch point.
Make an axis intersecting 2 of the planes, make a second axis intersecting one of the first planes used and the third plane.
Select reference geometry and get point, select intersection and click the two axis as your selection.
Another method is to start a 3D sketch then place a point that has an on plane relation to each plane; I believe this will be the intersection point.

Yes that works too!
3D sketch......point.....coincident to each plane
Or, select 2 planes and create axis. Then create point by selecting axis and third plane using intersection.
Many ways to approach the task.
Just sketch a point...constrain it to be "on plane" for all 3 planes.
Could be done as a 3D sketch, or as a 2D sketch on one of the planes (point would automatically be "on" the one used as the sketch plane, so then you are just adding a couple more "on plane" constraints to lock it down).
