You may want certain ads to appear more often within the slideshow presentation. You can do so by copying some of the current ads you have and dispersing them throughout the journal.
What to do:
Click "Ok" when the dialogue box pops up and asks asks you to confirm.
A duplicate ad will appear, labeled as "copy" under the sponsorship level.
This duplicate ad cannot be edited (only the original), but any changes you make on the original will take affect on the copy.
You can then have the system display the copied ad in other sections of the journal by changing the sponsorship level.
