It's not a critical issue.
1. How could I put filename which contains variables?
After I define a variable `time` with a value of `20150609`. I want to use a file `/my/file/path/sample20150609` as a file source.
In `file` field (filename) in file source block, how can I refer such a variable? I put variable name in the field, but it seems the GRC regards it as a string literal.
2. Every time before I run the GRC flow graph, I want to clear the reports (console log).
I think it is possible if I put something in `.grc` file in the home directory. But, I have no idea about that `something`.
