Can I use DistribTool to remove distribution rights

I'm using DistribTool.jar to assign rights to a lot of items to a distributor.  It works great!

However, I would like to be able to remove distribution rights for a specific distributor the same way.

I cannot find anything that says there is any other possible value for the action attribute on the request tag except "create".

I am not a java programmer, but I have looked at the DistribTool.jar source, and it doesn't appear to look for the "action" attribute at all.  But I'm probably missing something.

So, is it possible to use DistribTool.jar to remove distribution rights, and if so, how?
