BuyCpanel Migration

All BuyCpanel customers accounts where migrated into the cPanel Store. When looking at the cPanel Store, I see my migrated Licenses. But I cannot cancel any license. I can only buy additional licenses. While that is a nice idea from a sellers point of view, I would like to be able to buy and cancel licenses :-) The Knowledgebase is not offering any information about how to cancel a license. BTW: A way to export the whole licencelist as a CSV/XLS would be nice too. The cPanel Store is lacking some features. Perhaps there are other BuyCpanel customers here, which be able to add some remarks too. Thanks.
