To pull todays files through sender SFTP

Hi,

I have a requirement in which I have to pull only today's files through sender SFTP channel from vendors SFTP server but there are previous date files are in the same directory.

Is there any configuration is sender sftp channel through which I can pull todays files.

I have configured schedules but it keeps getting the files of different dates too.

Help would be really appreciated.

Thanks
