How to change length of multiple stills in video?

[erinh68655055]

I have added hundreds of still photos to a project to make a highlight video. I should've changed the duration of still clips before doing this as the default setting was 5 seconds and that makes the video seem too slow. Is there a way I can change the duration of each clip and apply that change to all of them that I've already inserted into the video? Trying to put together a video for my graduating daughter. Working in Photoshop Elements Premier 2018. Thanks in advance for any help!
