Import and Export documents with original name


So i am playing around with obsidian and i am liking it a lot. I do have a question about import and export of documents and their file names.

When i import (drag and drop) a PDF file with name Thisismyfile.pdf, i can see this name within the note, which it good. But when i click it and a preview is shown and press the download file button within that preview, it downloads the file with a string of random characters and not with the original name. Can this be done with the original name?

Thanks in advance.
