Hi Daniel
Try to use CTS IMG project outside of CHARM which you can then use to filter in STMS, see screenshot below:
This is a screenshot from a system where single import is active which means you don't see a big truck anymore.
After you filter on the CTS project however, you'll see the big truck appear "import project" next to the monitoring icon (see above screenshot).
You should be able to leverage that filtering / button to schedule in import job for a specific project.
