Enable Select Multiple Frames Option when Adding Animation Element > Select Frames

Please consider adding the option to either shift / Select multiple frames when you are Adding an animation element from within the App.  I had to rebuild an animation sequence on the stage and didn't want to drag and drop the same images from my desktop to avoid making the app size larger.  Adding one frame at a time is very tedious when you have to scroll past a lot of assets in your app to find the one you need. Especially when the Select Frames panel takes 5 secs to load each time you want to select a new frame. When you have 20 frames to add, its time consuming.
