I'm guessing not, but could stuff found on Autumn Leaf Isle be useful in repairing/adapting home-world tech to work in-game?

Also an additional question, I've been seeing talk of the D-Streams being able to store items and stuff in them but I can't find this information on the Digivice post.

...Is this a thing they can actually do and if so, what's the limit to what they can store/how does a character go about learning how to do this and/or storing things in them?
