SAVE A COPY changes location

I seem to remember that when you wanted to ‘SAVE AS' a PNG, you could do so in the first 'SAVE AS' window and it was there in a pull down menu option. But in recent years it required clicking on 'SAVE A COPY'. Doing so allows the PNG option to appear. But I often adjust the location/director/folder where I am saving first (it is at the top and I work down), when I click 'SAVE A COPY' it resets the file directory. Meaning I often don't notice, and it saves to the wrong folder and I can't find it. Could save to folder stay the same whilst you click ’SAVE A COPY’?
