LAC 的英文分词方法可以调整吗？

例如：
```
Vue 3.x 的Pre-Alpha 版本。后面应该还会有 Alpha、Beta 等版本,预计至少要等到 2020 年第一季度才有可能发布 3.0 正式版;
```
上述文本，我希望Pre-Alpha 为一个单词，应该怎么处理？
如果全部需要自定义词典，量太大了

Start by reproducing the provided Chinese sentence and checking how LAC currently segments “Pre-Alpha”. No files, tests, or entry points are named, so first locate the segmentation and dictionary-configuration paths; done should include a clear way to keep such hyphenated terms together without requiring an impractically large custom dictionary.
