CVS WSAD too many branches displaying

Using WSAD 5.1.2 on Win2000 with CVS 1.11 on Linux server. We have many branches that display in the CVS Perspective that aren't relevant to our developers anymore such as old dead-end branches that have long since been merged to the main (HEAD) branch. We would like to be able to filter out some of these branches so they don't display to the developer. The only way I can think of is to try to delete the branch tag (cvs rtag -B -d ), but the cvs documentation warns not to do such a thing unless you really really are sure and I really don't want to remove the tag... I just want to unclutter the developer's view. Any ideas? TIA

To answer my own question, we did the delete branch tag as shown below as well as deleting the "root_xxxx" version tag that wsad creates behind the scenes. It works, but the tags are still "remembered" by WSAD. To completely clear them you have to go into the CVS perspecitive, right-click each project under the Version icon and select Configure Branches and Versions. In this dialog click Remove All.
