Restrict blastp search to set of specific species

Question

[emi]

I want to perform a blastp search on a set of around 200 representative species with a list of known taxids. Is it possible using the web browser version of blast to efficiently limit my search without manually entering each of the taxid I wish to include?

I don't think so. You have to enter the taxID's in the organism box and use a + sign to add more than one. So says the in-line help.
