Is it possible to design conditionally executed tasks in Bamboo?

For example, by branch name you might want to execute different tasks (regress testing in release branches instead of massive integration tests for example).

Is there a mechanism to do that in Bamboo's UI?

Atlassian Labs have now provided this functionality as an add-on: https://marketplace.atlassian.com/apps/1219706/conditional-tasks-for-bamboo?hosting=server&tab=overview

Only available for versions 6.7.1+

Update:

This add-on is only supported up to Bamboo 7.0.6 and conditional tasks are a standard feature in Bamboo 7.1+
