Automatically import requirements to SILK using xlsx?

Hello all,

In my project it is more convenient to use an xlsx input file + mapping file for import (later updated) requirements in SILK, but the API I could find is using an xml files as an input (please, correct me if I'm wrong).

Basically I want to "automate" the manual step for update/import (select the xlsx and the mapping and click OK) - is such an option available?

If there's no alternative to the xml input format - my xml needs to follow the schema provided?
