Have a field toggle a task request

Have a field toggle a task request

I would like to be able to see a feature where a particular field can toggle a task request. For instance, when creating a new user account we have multiple accounts that the manager needs to be able to select from. I would like to have it be setup so that if they select the field "Email Account" and select "Yes" that it would create a Task to create an email account or if the select "No" it will not do anything.  Do you think this is something that could be incorperated in?
 
Thanks,
