Different endpoints for SPARQL SELECT/UPDATE

[cordawyn]

Some SPARQL servers use different endpoints for reading and updating data. For example, I'm using RDF4J server that expects SPARQL SELECT queries at http://localhost:8080/rdf4j-server/repositories/test and SPARQL Update requests at http://localhost:8080/rdf4j-server/repositories/test/update (old legacy convention, I know...)

Unfortunately, RDF editor allows only one endpoint for "Storage Locations". What about an option to have "split endpoints", when adding a new storage location?
