Deleting (corrupt) sharestones manually via UI

[Eye-sys]

First of all I want to thank you so much for making it possible to manually edit global waystone destinations when in Creative Mode. It's really really handy, thank you so much for that.

I'd love for it to also be possible for colored sharestones.

I need this in my specific case because I use colored sharestones a lot in singleplayer, colors being very useful for me because they allow me to divide lists of destinations (e.g. brown for dungeons\caves, green for overworld natural areas of interests, blue for temples and shrines etc.) but they sometimes get invalidated.
(I'm 98% positive this invalidation happens when I edit the chunk where the sharestone is placed with Amulet, but I'm still looking into it).
My lists of destinations thus contain a lot of duplicates and it's kind of annoying, particularly because they are long lists already. If I could edit the destination lists the same way I do with global waystones I would simply delete the duplicates easy peasy.
