Hello,
It is possible to execute command lines for Capella.
You can find information on this in the embedded help: Help / Help Contents, then Capella Guide / User Manual / Command Line Support.
Command lines can be executed from a .bat file. If you use Team for Capella, you have a Jenkins for administration of the server.
You can use this Jenkins in order to periodically execute the command lines (e.g. update your weekly reports daily).
So far, the progress monitor is not supported by command lines.
It would need a bit of Java programming in order to support this, but it could greatly help you!
