iPad Mount

Would it be possible to install an iPad shelf on the blank space on the SQ-7 rather/in addition to the current mount? The screw in mount sometimes obstructs sightlines, and the left side of the SQ-7 is pretty bare. Most other boards of this size have one, like the GLD 112. Even if it’s only big enough for an iPad mini, or a small set list, that precious space is unused.
