Autosplitting big sprites

Question

My artist deliveres me pretty many sprites like 4000x6000 or like that for buildings and other big game objects. With game resolution and player sprite 300x500 it is absolutley reasonable. The problem is that i want keep unity 2048x2048 import setting, to leave a game chance be tablet friendly. Even without tablets, a pretty much GPUs today still can not handle 8k sprites.

So this big sprites need to be sliced in parts, maximum 2048 max side. For 4000x6000 it is 6 sprites. It's ok for game. The problem is, thats pretty annoying to split them manual in Photoshop. May be there is a import option in unity to split sprites so out of the box? Or some well known asset? Otherwise i just need to write a script. Or may be you could propostal a better approach to the problem?

In the import settings, change Sprite Mode to multiple. Apply. Then click "Sprite Editor". In this new window, click "Slice". Change the Type to either Cell Count or Cell Size and change the other settings to whatever works best for you!

yes, it will make the half of work but i still need to reassemble the whole sprite after sliding probably i should write a pretty simple script

oh no, it does not work the big texture is anyway 2048 max size, so the resolution of multiple subtextures is relative to 2048, that is very low quality.
