fuseki+tdb: create in memory dataset with union default graph

For testing, I would like to fire up a fuseki server with an in memory 
dataset and a union default graph.

Is this possible?

I can configure a fuseki server with an in memory dataset using --mem 
but I see no way to tell it to set a union default graph.

I can configure a fuseki server with an assembler that says use a TDB 
dataset with a union default graph, but it insists on the dataset having 
a location property and I see no way to tell it to use an in memory 
dataset from an assembler.  There is code to allow creating tdb in 
memory datasets.

On the command line, you can use:

--memTDB --set tdb:unionDefaultGraph=true

e.g.
fuseki-server --memTDB --set tdb:unionDefaultGraph=true /ds

or if the assmbler configuration has a location of "--mem--" (the 
internal name of anon in-memory locations) then you'll get a TDB, 
in-memory dataset.
