It's not "out of the box" for any of these, including max/maya, but the concept is really so basic that all you need is to strap together a simple tool to offset the module's transforms based on the difference between it's otherwise default transform in relation to the other module and the "attachment node's" transform....…
Thanks for the help guys. I can't believe I haven't seen Kevin's gears thread. Great stuff. It would be really cool if he did a segment in vetex #2 on his modular workflow.
