Unfortunately, no. (Or at least I don't plan to) I figure it'll cause more problems then it solves. It's a limitation built into reactors (since they always have 54 inventory slots; hence always free slots available when you need to have less then 6 chambers to connect pipes/tubes/other machines to the core).
I might still figure out a way to make it so we can connect to reactor chambers, which
wouldshould make insertion pipes work properly [on a 6-chamber reactor] (as well as giving several more surfaces to connect stuff to, which would be interesting to see the kinda crazy things people would make w/ it).
That, so much. That needs to happen.
