Doesn't appear so - if there is a commonality among the 200 specific workstations that separates them from all other workstations perhaps create a custom Tag for them and then build the query off the Tag.
We use a CSV text file in a specific location that you can populate with the machine names, epo regularly runs an import and tag as %Whatever% based on the contents of that file, or you can run it manually.
We also use variants of this a lot where you have over the small number of entries that explicitly stating the names in the TAG can handle, this used to be somewhere around 50 , not checked it recently I must admit.
Unfortunately I don't have that level of access to ePO yet. I can only pull reports based on what's currently configured in ePO or have my team lead make the changes to the server configuration. As you can see from my screen shot, these are the only items I can filter my query by. I have to add a line for each machine equaling the machine name. Until I can convince my lead to create a Tag for these systems, I'm forced to use this method.
