Isometric tilemap renderer chunk mode and atlases

Hi! As I see in documentation for tilemap renderer modes, if I choose chunk mode and pack all sprite in one atlas, it should look okay, without any visual artifacts:

Separate sprites:


Union in atlas:



But I have atlas with really big count of sprites and this is necessity for me, so, this atlas has many texture pages AND when some sprites on tilemap located in different pages, these sprites draws with visual artifacts (like in first image)

So, maybe someone know, is it possible to solve these visual artifacts when sprites in different texture pages?

Yeah, I know, that I can create atlases with bigger texture size, but I can't do it because of inside technical reasons. Also I can't use individual mode, because it will incredible increase batches count.
