Kimberly,
There are many of us that are requesting this as well (hopefully your interest will assist in getting this going sooner) - see this existing thread and a mockup of what I thought it might look like:

I believe if you contact your CSM (Customer Success Manager) that they can get you added to the feature request as an interested party.
As you can see in the other thread Boris mentioned it has an id of: CR-236572
While your request was talking about just slide publisher - I think that if this gets fixed in the web interface - it may then flow through to slide publisher in the same manner.
