Set up Excel to always create backup files by default?

[EVX11]

Is there a way to set up Excel to ALWAYS create a backup for EVERY time I save ANY file over an old one?

That is, without having to go to File > Save As > Tools > General Options and checking off "Always create backup" for each and every file for which I want backups created?

I'm using Excel 2010.

Sorry if this is a duplicate question, but I could not find this via search.

Thank you.
