In our project the PVCS repository is branched into several workspaces But
through Hudson I can only poll default workspace not any other workspaces
branched from it.

Is there any option with this plugin to switch workspaces

How to set different workspaces or speciy a label/promotion group while polling
from pvcs.

Most of the options provided by pcli command are not there in hudson
Is it possible to get the basic ones atleast
