Space in worldmap editor spreadsheet

[Emmy]

Is it possible to increase the number of spaces here without hurting the spreadsheet code?



Before you ask, I am safe in worldmap (2601/3545).   I am using the propositions hack to write Extra Battles, with the same instructions for all of them (go to thief fort). I didn't notice until now that I'm running out of space in the box drawn on the spreadsheet.
