The batch processing and modeler are mising the 'iterate' feature, and this type of batch processing + merge functionality will be useful. I have a tutorial on how to write a bit of pyqgis code to do this that shows exactly the use case you have. But it can be used with any other processing algorithm. https://www.qgistutorials.com/en/docs/3/processing_algorithms_pyqgis.html [image: Logo] <https://spatialthoughts.com/> Ujaval Gandhi Spatial Thoughts mobile: +91-8095684687 email: uja...@spatialthoughts.com [image: LinkedIn icon] <https://www.linkedin.com/in/spatialthoughts/> [image: Twitter icon] <https://twitter.com/spatialthoughts>
