Thanks,
It's doable, not to diffcult to implement, maybe in a near future i will try to implement them.
The problem in automation of such things is to guess a rule of thumbs for thing like how to intersects the dividers, and how to join them.
There are many techniques, a long divider in one side and many small dividers, or an intersecting grid of two long dividers (as an example of only one crossed dividers).
I'm working on a different porject now, but, I'm planning to return on developing the BoxAuto plugin in the near future, stay tuned.
For now you could take a box auto generated and modify the divider and copy and paste and then place and trim the reatining pocket.
This is what I do when I need a more complex work on the auto generated box.
