download location for attachments in gmail

Dear fellow Mac users (I'm new to Mac so sorry if my question seems a little basic)

When I download attachments from gmail (in Safari) I would like to decide where the file will be saved on a file by file basis (and not have one allocated destination for all downloads (currently the 'download' folder. Any suggestions as to how one might do that? As things stand I have to download the file and then go into the download folder, copy it and the paste it in the folder that I actually want that particular file.

I hope that my question is clear.

Best wishes,

Greg
