Version 4 has a contribution from Timur: "Added remove air option to schematic swapper. 3 lines of code, but still may be usefull for somebody."
Version 3 centres the schematic around the marker block, and also removes the requirement to have the schematics placed under a 'filters' directory. Put them wherever you like.
Version 2 adds a feature requested by /u/Anguiish where you can specify a directory of schematics and have them randomly replace the found block.
How you use this new feature:
Put your schematics of different spawners in a directory under 'filters', check the box on the filter, and type in the name of that directory. When you run the filter on a selection area a random schematic will be swapped in for each block that is found.
The attached file Village.zip has schematics for a village.
This filter replaces the nominated block in the selection area with the contents of a schematic file.
