Need a function to modify the rotation center point of Items

While using Vtube Studio, I found that the pinning position of Items (or perhaps layers) and the center of rotation are not together, and it is not possible to adjust the center of rotation of Items.

It felt counter-intuitive to use at certain times: for example, Items garments that need to be articulated from the neck will detach from the neck articulation when certain axes are moved more. It seems that the Items are rotated according to the geometric center and not pinned in place.

In another PNG clothing I tried to solve this problem by moving the center of the clothes image to the neck position. But not all garments are published as images, more often they are Live 2D and they can't modify the center of rotation.

So I wonder if it's possible to add a function to specify the rotation axis of the items.

在使用Vtube Studio的时候，发现挂件的钉固位置（或许是图层）和旋转中心并不是在一起的，且无法调整挂件的旋转中心。
感觉在某些时候使用起来有些反直觉：比如需要从脖子处衔接的挂件服装，它们会在某些轴移动幅度比较大的时候从脖子的衔接处分离。
似乎挂件是按照几何中心旋转的并不是钉固位置。在另一个PNG服装中我尝试将服装的图片中心点挪到脖子位置解决了这个问题。但是并不是所有的服装都是以图片的形式发布的，更多的是Live 2D，它们无法修改旋转中心。
所以不知道是否可以添加一个指定物品旋转轴的功能。
