Some airlines have MM/ATA refs on the card or log cover that you slip in to avoid write through to the next log page.(yes!that's how to avoid it)
Anyway they are usually good for chapter and sub chapter but if your co. requires more like page and paras then you are screwed anyhow.
If you have the luxury of a walkie you can always load it on to some seat shiner in control!
Incidentally and off the track slightly;if your co./airline has maint manuals on a LAN or other type of network whose responsibility is it to do the amendments???
