How can I update a PDF file without changing the URL in Shopify?

Hello everyone

I have a Redirect Url to a pdf file (stored in shopify) that needs to be updated from time to time. The problem I have is, it looks like when I replace that pdf, shopify keeps the original and adds a new version, for example instead of the file being named “User_Manual.pdf”, the file is “User_Manual.pdf?v=170307316”. Is there a way to redirect to the file without having the folders and version on the link? I know the file has an URL Handle but is it something I can use to simplify the path?
Thank you
