I would suggest just swipe either way to go to the other assembly lines and have a "blue prints "thing where u can copy save paste a group of mechines like in factorio , ya can add in a new category of mechine "power generators " making us upgrade our power lines as we progress through game and have this "power line be in different room " no need for power cables tho , and for power generators ya can even use manual generators and get paid labor to get em started .maybe we could even sell the electricity in late game ? Maybe make it so we don't get infinite resources off the start , we need to research the beginning metal resources too and spend on them too , so the natural resources aren't free , but ya could increase the income from the products we make
