I am using Quick OSM in QGIS 3.12.3-București. When I 'Run query' for a specific geocodeArea, eg London, and I specify the 'Key', eg Highway, but I leave the 'Value' blank; (img 1). The result is one layer in QGIS with all of the Values of highway on it; (img 2) (well its 3 layers - Nodes, lines and hatches. but for the sake of this question, let's just say it's one layer).

What I would like to achieve is to have all of the Values for the Key (eg highway) to be on individual layers in QGIS. So I can avoid having to 'run query' for each and every value of 'highway'. As this is a laborious process and there must be a faster way.

I have looked into the 'Overpass query' method, but iv'e only found it gives me the same result of everything in one layer.

Is there a piece of code I can add into the Overpass query to tell it to load the values on to separate layers? Or is there a way to split the layer after it has been loaded, into separate layers of the Values of the Key?

This question provides the answer, which is to use "Split Vector Layer" from the processing toolbox. Beware that the result is NOT added to the map - each new layer is saved as a geopkg in the directory you specify (or a temp directory you'll have to go hunting for.)
