Hi, apologies if this has been answered before...
Let's say that I have directions to get somewhere in the form of a column for map page numbers and each row is the page number and the square references. How can I reverse the route?
e.g. change....
29 E1 F1 G1
30 B3 C3 C4 D4
31 E4 F4 G4 H4 H5
to
31 H5 H4 G4 F4 E4
30 D4 C4 C3 B3
29 G1 F1 E1
bearing in mind that page numbers may not necessarily be in order.
