Is it possible to iterate through each well one at a time with only one visible well at a time?

Thanks in advance for this neat tool. I have been able to only get this to work with 0,0 (row, col). What I am interested in doing is on update of 0,0..to then re-draw showing 0,1 (row, col) and so on...Have not been able to figure it out without it showing the whole plate.
