Is your feature request related to a problem?

I think it is usual for people to create a build to look at their stats in PoB, and also follow a PoB for their build. It would be nice to see a feature allowing to select an origin build, items similar to which's to search, and a destination build, that allows you to diff/import into that build. A feature to complement this would be split-screen for two builds.

Describe the solution you'd like

When opening the Trader window, a field is there allowing to specify which build of the ones you have locally to compare with, import into.

Describe alternatives you've considered

You can import the item into the origin build, copy it, open another instance, open the destination build and paste the item.
