Deleting multiple analysis reports in one go?

Dear Studio 2014 experts,

I have one trivial question: does anyone know whether it is possible to select multiple analysis files under Reports and delete them in a batch instead of deleting them one by one?

I tend to run analysis a lot and these reports quickly accumulate.  It doesn't affect the performance at all, but I would like to clean up the report list from time to time.  I haven't been able to find a quick way to do so.

Thank you in advance for your input.
