How can I call IMPORTSIL with a local file?

Hi.

I'm developing a C# application that interfaces with X3 via web services.

Now I need to call a procedure (via web service) that will use an import template, but I'll pass a path of a file stored locally on the client computer.

Is there a way to use IMPORTSIL with a local file instead of a file located on the endpoint?

The same way you do when imports a file from X3:

Thanks.
