It's unlikely I will be able to add or change anything for the next 2 weeks at least.
I'm at work and suffer currently from a very very slow connection (this page alone took like 2 minutes).
If I have a corporate network I can hack my way into I will update this, but for now it will have to wait till I'm home (2 weeks+ after weekend).
You can simply open the file with notepad or your favorite texteditor and add the itemID's in the same fashion as the rest of the list.
Keep in mind that if you want to add a item at the bottom of the list, to add the > , < to the line before and remove it from your addition (the last line doesn't have this).
Regards, Liquid.
