When working with large vector data sets in QGIS is there a method where you can ask QGIS to only load a small subset of your data? I know that this can be done based on attributes using a virtual layer, but I am wondering if it is possible to do this for multiple large datasets and to get the same geographic coverage. Sort of like clipping the same geographic slice out of multiple data sets, except that I don't want to clip my data. Is this possible. I am not sure that I have the language to describe it.
