Yes, but if per cell it is probably much more programming work for RevEd, and at 56 variables at least i would find it too many to click, and it would also need indication of which cell have which base.
There are already three different base columns. I guess simplest is to add a fourth column so all vars are displayed in all bases. hex value need only a very small width. The ASCII column could get more narrow, or hex values inserted in same cells as the ASCII like so: 5C '\'
