LR4 Function Missing in LR5 - Cannot automatically add captured photos to a running slideshow

I just purchased Lightroom 5 for creating a photobooth in which tethered capture photos would be automatically added to a running slideshow as I had seen done with Lightroom 4. However, I now find this feature is not available in Lightroom 5. I am VERY disappointed. Newer releases of software should add rather than remove functionality. Having just purchased Lightroom 5 I should not have to go back and pay for an older edition to gain functionality.
