Improve the process of adding support gems to skills not coming from gems

This always frustrates me so much. You can't add them directly to the group as it's locked and can't be edited. PoB says, however, that socketing support gems into the item it's coming from, if any, will automatically add them to that group. But creating a new group for the item slot DOESN'T in any way take into account that link, even if you chose the skill as your main, and so you are left completely in the dark and have to try every gem out yourself. It's not so bad if at least the skill has an equivalent in available active skills, like the level 30 Reckoning from the Surrender, you can simply add that skill to the group and forget the item's skill exist. It doesn't work great however for every other skill, and so I'd like to have this oversight to be fixed. Thanks in advance, you rock!

P. S.: Why do the skill groups even have to be special? Why not make groups for such skills editable, but only prohibit changing the main skill of the group? This also lets potentially to see what a skill does and other things about it w/o having to look them up online.

このIssueでは、ファイル、テスト、エントリポイントが指定されていません。まず、アイテムが提供するスキルのスキルグループを作成してロックするコードを見つけ、次にsupport gemsとアイテムリンクがどのように表現されているかを確認してください。アイテムが提供するスキルがリンクされたsupport gemsを考慮し、意図されたグループ情報または編集動作を外部検索なしで利用できれば完了です。
