I added new 'pages' or tabs to cockpit with one or related variables for all stations on each page. For my use, this makes it easier to scan the status. I saved this config on the ASTER home directory as "byVar", while the previous config is saved there as "byStn". I intended to delete the station tabs from the "byVar" config, but I could not do this from the toolbar at the top of the window. Apparently the station tabs, generated in the xml file, are not classified as 'pages'.
Amazingly, everything appears to be still running okay...
