"HIDE MEDIA FILE' in Playmemories

Hi all,
 Back in 2013 Playmemories Home had a choice under 'Edit" called "Hide Media File'.... If you clicked on a picture or video you could actually hide it simply by clicking on "Hide Media File' and then you can see those files by clicking on 'View' - 'View Hidden Medie Files'. It was a GREAT thing to have.  I've downgraded all the way back to PMB 2.0 because "Hide Media Files' is needed at home.
Come on Sony..... Get this put back in PMB, I'm sure many others can use it.
