Concatenate sketches

[linsalrob]

Hi

Is it possible to concatenate multiple premade sketches and then search against them in a single search?

something along these lines

dashing sketch *.fasta
cat *.hll > combined.hll
dashing sketch new.fasta
dashing cmp --presketched combined.hll new.fasta.w.31.spacing.10.hll

Thanks

Rob
