Batch add key frames to beginning and end of video clips or photos in the timeline or Effect Control

[EricSol]

When creating a photo montage, it is very tedious to add keyframes - one-at-a-time - to the beginning and end of each image's 'Position' and Scale'.  

And then if you want to add a transition effect, that means manually moving each keyframe so that its movement is constant.   I'm getting tired just typing this explanation. 

PLEASE PLEASE PLEASE add a 'Batch Add Keyframes' feature with the ability to select the parameters we'd like those keyframes to be placed on.   This would be an enormous time-saver to anyone creating a photo montage.

Thank you
