Editing multi slide video using the Edit Video Timing window

I have a project with a video that I have playing across multiple slides.

Right now I only see a manual interface in the Edit Video Timing window to adjust the duration of playback on each slide, meaning I have to drag the marker around on the screen with my mouse to try and align it with a specific time stamp.

Is there a place somewhere in Captivate Classic to type in specific time values for per slide video duration, like there is in the slide duration in the Timing window for the slide, so I can be precise without having to drag the marker around on the screen?
