Of course you can!
When adding a potential task through one of your Slack channels, the Any.do Task Detection Technology will detect your task and send you a Personal Message.
You can then choose if you wish to set a reminder for that task or simply assign it to one of your colleagues.
[If you set a task yourself, the same options will will display]
Once you click on 'Assign this to...' you will be able to choose a team member from your contact list.
