Replace characters in attachment names for HTML exports

Hi everyone :sun_with_face:

When we export attachments via HTML export, the file names have the + character instead of underscores. This doesn’t happen when we download an attachment directly from the page = the filename shows up as expected.

We want to transfer some older attachments to our records management system on an on-going basis and would prefer not to have to rename all of the files. Is there a way to specify the naming strategy for attachments from HTML exports?
