Can unity psb importer leaves more space for each sprite?

Can unity psb importer leaves more space for each sprite?
When unity imports a psb file, it generate a sprite for each layer, but the problem is, it leaves zero free space for them, it squeezes each sprites into a frame that fit perfectly, this might be good for saving ram, but if I draw more stuff in that layer, it will be cut out, and I will need to redo the rig! And the auto geometry in skinning editor is not working properly because of this, some part of the sprite is not included! I have no idea why unity didn't notice this, or is it because there is something that I don't know?

 

I mean, I know I can do it manually, but I would need to do it once for each layer.
I think "extrude edges" is the tool that I am looking for, but it is not working at all, no changes.

 

Any luck on this? I'm running into the same issue, where PSB import doesn't seem to extrude edges around the layers.

 

@Ted_Wilkman I think you already addressed this in https://forum.unity.com/threads/psd...sheet-and-sprite-meshes.1096648/#post-8471417. I misunderstood what the extrude tool was supposed to do. I thought extrude added padding around sprites, but really all it does is KEEP padding around sprites. The transparent padding needs to already be present in the image.
