Look at it like this, you have created a tile strip with 44 tiles in it. You import it, then trim it, then have to manualy go into each tile to set the collision polygon to match only the visible pixels of the sprite not the trimmed transparent pixels added on all side.
Then in your graphic tool of choice, you create different color variations of that same tile strip. You import the various colored versions of the tile strip. You then have to go through each one manually adjust the collision polygons on each frame (44 frames for each tile set) multiply that by about 10 sets of tiles and you can see that it gets pretty tedious...
So being able to either A. Have it stick the collision rectangle to the visible pixels as an option, or B. be able to copy the collision polygons from one animation to another (especially if they have a 1 to 1 match up of collision polygons between the frames. For example if visible pixels in frame 1 of SPrite A match the shape of the visible pixels of frame 1 of Sprite B's animation then copy the collision polygon between them.
Thanks...
Unless I'm completely not understanding what you're writing here, you can already do this. Import all your sprites, as many animations as you want, then go into any frame on any animation and modify the collision. Then right click and apply to all animations. This will copy the collision shape to all frames of all animations.
