Yes, you can!
You simply have to use the Update all feature.
This feature lists all imported shapes in the active presentation and allows you to update them all or to select a subset (see picture below).
To help you decide which shapes should be updated, a click on any items in the list displays and selects the corresponding shape.
When you click update, UpSlide tries to update each of selected items using the contents of all opened workbooks. The shapes for which update has failed, by excess or lack of potential source, are then put in a separate list (see picture below for an example).
You can then open the find the source dialog box directly by double clicking the problematic items
