minor inconvenience with pdfLaTeX export function in wxMaxima



I am now using the  pdfLaTeX export function in wxMaxima frequently. The 
only inconvenience is that when selecting "Export" I have to change the 
type each time from HTML-file to pdfLaTeX-file and after changing that 
type the filename is still displayed as myfile.html, so I have to change that
one also to myfile.tex
Is there a workaround for this? Maybe a config-file which can be edited?

kind regards,
hugo
