Elements 2019: Hidden Files 'Save As'

With the usual apologies for no doubt asking a dumb question, here goes.  I have a sprinkling of confidential photos that I store in Elements as Hidden Files.  If I edit one of these photos and want to save the edit without over-writing the original ('Save As') the default seems to be that the newly edited version is stored in Photos on my C drive where of course it is no longer hidden.  To get around this I 'Save As' to an encrypted USB drive, but is there a simpler solution?
