Turning pictures into frames

When clicking “Open File” and selecting PNG pictures (2 or more) the pictures get into the playlist (not into any track). Can you make it so that all the pictures in the playlist turn into keyframes (in a chosen track) by using a tool? I can insert them into the track by pulling the picture to the track but if the pictures are too much it’d be a problem, so please add it as a feature, thanks!
