Is it possible to manually map information to IFC (e.g. feature/corridor object to IFC entity) in OpenRail/ OpenRoads Designer?

I would like to manually configure the export to IFC selecting in OpenRail designer. is there a built-in funcitonality that allows datamapping to IFC? Is it possible to read the content of the .rose files in the directory C:\Program Files\Bentley\OpenRail Designer CONNECT Edition\OpenRailDesigner\ECSchemas\RailwayIFC carring the IFC implemented schema?
