It would be awesome if there could be a setting (raw option) to specify an existing AWS Profile to be used for a specific site. I can kind of do that now by setting
AWS_PROFILEenvironment variable and then launching the WinSCP, but I would prefer to have multiple sites referencing different profiles. Let's say there would be
S3Profileraw option set in the site causing the WinSCP look up the credentials for that specific profile.
