Implement a "update build" function

Is your feature request related to a problem?

One of the things I use PoB for is to check my current builds. For this purpose, I regularly import these builds into PoB via the existing function "Import/Export Build" and there via the area "Character Import". However, this import often (or every time) changes the "Main Skill" and settings which skills can be added to "Full DPS".

Describe the solution you'd like

As a user, I would like a button that directly updates the current build without a selection dialog. As an option, this function should allow or disallow changes to the current settings for Main Skill, Configuration and Full DPS.

Describe alternatives you've considered

No response

Additional context

A suggestion would be to put this button as "Re-import" next to the two buttons "Save" and "Save As".

首先跟踪现有的 Import/Export Build 流程，尤其是 Character Import，以及 issue 中提到的 Save 和 Save As 控件。定义 Re-import 按钮应如何更新当前 build，以及 Main Skill、Configuration 和 Full DPS 设置是保留还是替换；在无需选择对话框的情况下该行为能够正常工作，即视为完成。
