replace tour.html by index.html in the template ?

Hi,

I'm trying to replace "tour" by "index" in the kmakemultires.config and also in the vtour-mres.config. It creates a separate "index.html" in addition to the "tour.html". Thing is my index is not working (black screen). I know i could change the name directly on the generate html file, but i'd like it doing automatically.
Is that possible?

Thanks.
Steph.
