Interactive Video and Fractions of a second

Great tool and I amhoping that this feature already exists but I cannot figure out how to pause video or set the text tools to display/pause except on intergers of a second.

For my sports presentations I need to be able to pause the video on a specific frame (or at least close to it).  When attempting to set the "Display time" for the Text tool in an Interactive video I would like to be able to set it to something liek 0:12.5 seconds or video frame #75 or some other time format.
