Merging alternates
If you want to combine parts of an alternate with the official version, you can use the merge option from the Wireframe menu or from the context menu in the Navigator panel.
Selecting "Merge with Official" will add the contents of the selected version to the official version, to the right of the wireframe contents.
If the notes in the alternate are different than the notes in the original, they will also be merged, separated by a dashed horizontal line.
You can then manually edit the contents to create a new official version that is a combination of the preferred elements of each version.
