Show custom actions in the "Message Event" list when creating new plugins
Currently, only system messages are available when creating/registering new plugins (e.g. Create, Save, Update, etc.). Users should be able to select from active custom actions that have already been created as well. Microsoft's plugin registration tool currently supports this.

This should already be the case… but you may need to close and re-open Visual Studio in some instances. This will be improved in v7 such that they will show up immediately after creating new ones in CRM.
