Is there a limit on the number of cells in "saved Defined Cells" option

I am trying to set up my system to only save, and load, selected cells. I understand that I can select specific cells, right click, and add them to the list, however, I have 2 worksheets that contain tables, that can grow to any size, so whenever I select the full columns (A:E) for example, right click, and click “Let users save and restore selected cell”, the system hangs - is this because there is a limit on the number of cells you can add, and if so, can I specify complete columns or worksheets somehow?
