How to get report PROMPT values in publication set up

Hi,

I am creating a publication so that my report gets distributed automatically every week.

I have the below prompts which will give the start and end dates in this format DD/MM/YYYY for the previous week.

Now my question is, is it possible to use the value from those prompts in the filename (i.e. in the yellow highlighted section of the image below)? I want the filename to be "HK_TAR_DDMmmYYYY_to_DDMmmYYYY".

Thanks,

Jay
