Task Management Changelist disappears

I am using Task Management with Pivotal connector. When creating a new task, IDEA creates a nice changelist for me. After finishing the work I commit everything. Then switching to a new task, which creates a new changelist and removes the old one. But now, I have to fix a bug with the old task. So, I switch to the old task and all my windows reappears, but no new changelist is created for this.

Is it possible to create a new changelist for old tasks?
