You can easily edit cell command numbers in the cell table. Just enter a command number that matches the desired command in the ******** cell commands: section of the main GUI. If such a command doesn’t exist, PgcEdit will warn you by marking the cell command box pink. In this case, go back to the main GUI and enter the desired command.
If you enter a cell command, the next cell must be non-seamless. PgcEdit will warn you about this by marking the seamless box pink.
