filter with regex match in scripting plugin

I would like to use a regex for filtering from the script plugin. I have found that I can enable the regex matching after creating the filter using the following construct:

```
myfilter = someAttribute == "someregex"
myfilter.getUnderlyingQuery().filter.setUseRegex(True)
subgraph = g.filter(myfilter)
visible = subgraph
```

While this works, it seams a bit verbose and implementation specific to have to run the **myfilter.getUnderlyingQuery().filter.setUseRegex(True)** statement like that. Is there a better way I am failing to see?
