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.

Das Issue nennt keine Dateien, Tests oder Einstiegspunkte. Beginne damit, den Code zu finden, der Skill-Gruppen für von Items bereitgestellte Skills erstellt und sperrt, und ermittle dann, wie Support Gems und Item-Links dargestellt werden. Als erledigt gilt, dass von Items bereitgestellte Skills verknüpfte Support Gems berücksichtigen und die vorgesehenen Gruppeninformationen oder das Bearbeitungsverhalten ohne externe Suche verfügbar sind.
