Automatic Level-Up Gem Option [QoL]

Title says it all. After a quick search, I could not find this specific suggestion so here it is. I want to suggest an option to automatically upgrade gems as soon as it comes available, similar to how you can stop a gem from leveling and remove the indicator. This option could be applied with a modified click such as control + right click, or shift + left click. It could be indicated in the inventory panel similar to halted gems, maybe instead of a [+] it could be [^], [=], [>], [X], etc.

Many times I will want to level gems from level 1 to the level I am at. It can be annoying at times to have to click level-up after every pack. Also when I make a new character, most gems I already know will be leveled to the highest I can go. By implementing this option, I believe players will still enjoy leveling gems without it being too intrusive to gameplay.

Sometimes you do not want to overlevel gem (CWDT setup, or high requirements).
But until is only an option I am fine with this idea

Could be like with trade configuration: set a max. level if desired. +1

But even more I miss to see if the gem level popup comes from a skill I actively use, or a gem in the 2nd weapon slot. Would really like to have a mark for the key an active skill is bound to, for the skill /key a support gem is bound to and/or (as said) for backhand socketed gems.
