Merge Academy more space

As I progress threw the different levels and find new items to merge, I am realizing that there just is not enough space do "fill" the orders.  The board is 9 spaces across by 7 spaces down which is a total of 63 available blocks to hold all of my mergeable items. I have opened everything up and do not have the proper space to have all my generators out on the board at the same time while trying to complete orders. I currently have 12 different generators but only enough space for 9 across the bottom. I have to keep 3 of them in the storage closet and switch them out when I use them. Is there a way to expand the board on the right side? There is more than enough room to add a few more columns. I will Show you in a screen shot. Thank you for any and all help with this matter.
