Dependent Field Mapping based on 2 criteria?

Dependent Field Mapping based on 2 criteria?

Is it possible to create a dependent field mapping (or 2 dependent field maps) that would allow for two variables to take place before the child field could be populated?

Example: IF "X" AND "Y" then allow dropdown choices?

If I have a task, and I have a dropdown box for type of task (call, email, letter), then I want to make the child field dependent on the parent field (call made, call left message, etc)...but I also want to make the child field dependent on the task being marked "Completed"

So it would go:

IF "Status"=Completed
AND "Task Type"=Call

Then, Field "Completed Result"=(picklist) Call Completed, Call Attempted, Left Message

OR....

IF "Status"=Completed
AND "Task Type"=Email

Then, Field "Completed Result"=(picklist) Email Sent, Email Received


Can I do that? That would be nice!

Thanks.
