Undoing a bundle in Microsoft Word will remove the necessary bundle formatting, allowing you to change and then recreate your bundle.
To undo a bundle, simply click the 'Create/Undo Bundle' button to launch the Bundle-Maker. Click the 'Undo Bundle' tab.
A single click of the 'Undo My Bundle' button will then remove the necessary bundle formatting, allowing you to edit your bundle. You can also select to remove all page breaks and/or key passage highlighting (key passages are discussed in the next section).
When you have finished editing your bundle (adding and/or removing materials), you can then recreate it.
