[TI-82] tag substring matches

I use timewarrior via the taskwarrior hooks, and I also use hierarchical projects in taskwarrior e.g. project:foo.bar and project:foo.baz. Now in taskwarrior I can see everything in the 'foo' project, i.e. when I say 'task project:foo' it returns both 'foo.bar' and 'foo.baz'. 

When the taskwarrior projects get converted to timewarrior tags, it rightly converts the entire 'foo.bar' project label to a task. But now, I can't find a way to get to get a timewarrior summary for all intervals of the 'foo' project. I can pipe the summary to grep, but then I lose the timewarrior convenience of adding up all the filtered times and other report features.

Does this capability exist already? If not, I suggest the default taskwarrior behavior of matching leading substrings ('task project:foo' matches all projects with ^foo.*).
