Automate creating 2d animations for many sprite sheets

Hello, sorry if this doesn't make enough sense, I'm still learning how things work.

I have created animations for a character sprite sheet so that the character walks across the stage. It looks great. Now, I know I could create animation controllers for each of the character sprite sheets manually, but is there some way to automate it, just like I can create settings to automatically slice and set pivots for my sprite sheets as I import them? I can't seem to find anything. Barring that, is there some way in code to make the animation/animator change which sprite it is using since all of the sprite sheets use the same positions? Like frame 1 is armor1_1, frame 2 is armor1_2, but instead it swaps it so frame 1 is armor2_1 and frame 2 is armor2_2 for example.

Thank you very much for your help.
