Agreed. I have a cable that I will be working on soon that will probably require splitting between two pages due to it's size. I'm not exactly sure how I am going to handle that yet.
There is a kind of workaround to this where you place a node with a graphical symbol for a page break on, then on your 2nd sheet you place another node (again with a symbol for a page break) and link the 2 nodes with a zero length bundle. In all my drawings I have a layer called Hidden which I would put the zero length bundle on, and then I Hide the 'Hidden' layer! This gives the appearance of a page break when in fact it is technically still one harness.
