Bookmarks can also be assigned as links to shapes and images. With multiple Bookmarks created across multiple report pages, a visual table of contents can be created to aid the user's navigation of a report. Rather than opening and browsing the Bookmarks Pane, users can simply click images or shapes associated with specific Bookmarks, and a back button can be used to return to the table of contents page.  

In the following example, nine images have been positioned within a rectangle shape and linked to Bookmarks in the report:

With an image or a shape selected, a Link formatting card can be enabled to choose between a Bookmark link and a Back link. In the following example, the France flag image positioned in the top right of the table of contents is linked to the France: Excluding Bikes bookmark: 

In this report, the back button image introduced in the Drillthrough report pages section earlier in this chapter is also inserted in each page of the report. Rather than return to the source page of a drillthrough action, a Back type link is set to allow users to return to the table of contents.

In the following image, a custom back button image has been inserted and set as a Back type link to aid navigation:

The combination of custom navigation and Bookmarks representing many specific views or reports contributes to an easier, more productive experience for users. When designed properly, the user often doesn't need to know which page or bookmark to navigate to or which filters to apply as this logic is already built into the report.
