Flat folder structure on Sync?

Is there any way to force a "flat folder" structure when syncing?

For example, my remote directory is:
Root/Folder1/File1
............/Subfolder1/File2
............/subfolder2/file3

and my local is
c:\Folder1

I am synchronizing directories and the folder I am synchronizing is Folder1 on the remote to the local Folder1. I want the files from all the subdirectories, but I do NOT want the actual subfolders (making a flat folder structure).
Result I want:
c:\Folder1\File1
..........\File2
..........\File3

Is this possible?

I also would like to know if this was possible with the C# library as I am also coding a utility.

No, WinSCP does not support that.

Are there possibly plans to?

Maybe if more people ask for this. So far it looks as a quite specific request.
