Possible to set a global file set?

Hello.

I have rather a large number of projects, and all of them are multi-module Maven projects. For every single module, I have to go into the Checkstyle configuration and set:

```
^src/main/java/.*(\.java)$
```

... as the file set for Checkstyle. Scanning my projects directory, this means that I'm going to have to type the above _638_ times. :grimacing:

Any chance of setting this file set globally somewhere rather than having to set it for every project?
