Label Selected Elements

Rather than manually applying labels to each of your elements, perhaps try the following.

1. Assign the desired label type (eyedropper existing, or use a favourite), you can then deselect the label tool.
2. Select all the elements that you wish to label.
3. Navigate to Document > Annotation > Label Selected Elements
4. Done.

It is possible to add this command to your Toolbar, for quick access.
