even manually i can't place fore example red sorter upon old yellow sorter. i need to remember settings. then delete old. put new and manually restore settings. WHY? it's mission impossible level to make these things easy upgradable? in current state it's just not usable at all... if you use several in your base then it doesnt matter but when you use 1k and decide to ugrade lines to next tier be happy to manually replace every 1k sorter... i think it's the main reason why this mod stay in 'funny thing' instead of 'everybody use it'...
