Engraving Carged Spells into wands

Introduce a new Rune Gem to open a slot in wands to engrave "charged spells" extracted from charged wands.

We could have a new drop to look forward (or a new method instead of the gem) to open a slot on a wand and for example add IS/Inhi/MiM/Cancel charges to an Ms32 LLF wand if you want max mana saving on the spells.

Or my personal favorite,  opening a slot in a Resu wand and charge it with cancel so you would have access to all spells avaible in game with that wand (hopefuly the rework idea I posted to Resu wand goes through to get the ms28). https://ideas.helbreath.net/en/communities/1/topics/48-rework-ressurection-wand-full-support

Once the charges reach to zero, you would just "recharge it" sacrificing another charged wand.
The UI/method could be added to Crafting Vessel list.

Another possible use, if the idea by Reise is adopted: https://ideas.helbreath.net/en/communities/1/topics/50-circle-10-spell-charge-wands, would be to engrave a Zwand ms20+7 with FoT/HF/ESW/Blizz.
