Can I change name of HTML file produced by slidify()?

I'm wanting to use slidify to produce multiple versions of the same set of slides using different cuts of the data (e.g. sales data per store so each manager can see how they're doing).

Looking at the documentation it seems that the slidify function allows specifying the .Rmd file input but not the .html output. 

I presume the only other thing that I need to create multiple versions of are the figures and the rest of the files (js, css etc) can be shared across all versions of the slides.  Is this true?
