For example I have 2 boxes, Box 1 Loader (stacking) into belt into Loader (stacking) into Box 2
I have Stacking research at 4

If Box 1 contain 200 Iron Plates, which is divisible by 4, everything looks perfect, no problem whatsoever
But if Box 1 contain 199 Iron Plates, 1st slot is 100, 2nd slot is 99, the loader will output one 3-stack Iron Plates onto the belt despite still having 100 Iron Plates left

Functionally, it is just a minor issue
But aesthetically, it doesn't look good when the belt are not uniform with many holes, my Factorio brain goes no-no
I have tried all the Loader stacking mod, still same result

Can this be remedy in anyway?
