Creo Illustrate - Remove multiple keyframes at once (?)

Hello,

I am creating a sequence to use in Vuforia Studio. I selected 4 parts and moved them up, then across, then down. Each movement created a new keyframe for every selected part. I want to remove the last movement. Do I need to manually expand the track, find the part, expand it, find the keyframe, then select and delete it - for every individual part - or is there a way to do this for all of the parts in the track at once?

Also -- if there is a help resource, documentation, or another forum where this or a similar question has been answered -- can you mention it in your reply?

Thanks!

Wes
