I think it’s really cool that we can build Iconic Items in the Demiplane character builder (per the Avengers Expansion). It works great, though I do think it could use a filter option when selecting powers to add to it, especially since the list goes through every power in the game. A useful way to filter these powers could either be through expansions (especially since the Avengers Expansion added a lot of new powers specifically for Iconic Items) or even by powerset, like they are in the main character builder.
