How do you store your items from different DLC’s?

For example do you store any main valley items on EI, or Wish Blossom Ranch or vice versa?

I wish we had more box colors so I could do some more organizing. Like as right now I do have some storage for some miscellaneous eternity island items but I haven’t started the other DLCS

Sometimes it just feels like it’s too much work to go to my floating islands or open up a DLC when I’m in the main game to put items in their proper place or to access something for a quest.
