I could’nt do it yesterday but I found a way to do it if you’re interested. You have to select the sprites of the animation you want to create a spritesheet in the order starting by the first one up to the last one and you can choose amon vertical, horizontal and compact spritesheet as weel: https://www.codeandweb.com/free-sprite-sheet-packer in this link you can do it, just clean the default sprite and choose the ones you want to use :) . I hope it helps you someway.
