If you want things like series and publication date on your Kobo, there are ways to do that without changing the filename. Series support for sideloaded books is automatic on a Kobo - you'll need to change the metadata management under Sending Books to Devices in Calibre to automatic instead of manual, and after transferring books eject your Kobo, disconnect it, wait until the new books have been processed and connect it again.

You can add the publication date as a subtitle - in the Kobo driver settings it's on the third tab, Metadata.
