我在给一个UStateTreeAIComponent配置StateTreeRef的时候发现，下拉菜单里只有指定Schema类型（也就是UStateTreeAIComponentSchema）的StateTree。我新建了一个蓝图类型BP\_StateTreeSchema继承自UStateTreAIComponentSchema，使用了这个蓝图Schema的StateTree并不会显示在下拉菜单里。根据代码StateTreeReferenceDetials.cpp ： 135也可以看到，StateTree会把他使用的Schema类型作为Tag放在AssetData里，而过滤的逻辑就是直接对比类型的字符串，所以子类Schema都会被排除。我知道用AssetTag是为了避免加载这些StateTree，但是能否有其他办法能让子类也显示出来呢？

你好，我本地测量下似乎是可以的，你要不上传个重现视频看下？

视频里展示了如下流程：

1. 先继承一个UStateTreeAIComponentSchema的子类UTestStateTreeSchema出来
2. 新建一个StateTree使用这个UTestStateTreeSchema
3. 新建一个PlayerController加上UStateTreeAIComponent，可以看到它并不能选择我们新建的StateTree
