Since storage can only be used from home nation and earrings are the best speed way to get home can we get a big increase in the number of charges these earrings can hold?

Right now it's 30, can it be boosted a lot higher please? I was thinking around 100-200+ or so charges. The low number and rather annoying nature of creation makes me frugal with it's usage which defeats the point of having it.

If not can the R/E tag be removed so we can buy them on the AH?
