SFTP connection with SSH tunnel (proxy tunnel)

Hi Rai Drive team
I was trying to connect SFTP server via ssh Tunnel option, which is not present in Rai Drive. Even I have checked most other providers similar to RaiDrive, and none of them offer this option. Can you please add this feature as soon as possible. (For example, WinScp offers SFTP connection with SSH tunnel, please incorporate similar feature to RaiDrive).

Thanks,
RB
