Use iceScrum (or iceScrum Pro) as IntelliJ Tasks resource.
You can choose tasks from your project and start them.
Be sure to take a look at the iceScrum & Intellij integration documentation, as it contains a full preview of this plugin.
Task titles (and reference ID's) are then added automatically to each commit so your iceScrum Pro version (as it have an integration with SVN / GIT) will know that some commit is about some task.
