There is only 1 "dispatch" directive. How can we have multiple virtual regions? If we emit "taskwait" directive in AST then we will have multiple virtual regions. 
I have looked at combined directives but, in them we have multiple directives.
```
#pragma omp parallel
  #pragma omp for
```
becomes:
```
    `-OMPParallelDirective 0x1311798 <line:10:3, col:24>
      `-CapturedStmt 0x1311770 <line:11:6, col:21>
        `-CapturedDecl 0x12a5770 <<invalid sloc>> <invalid sloc> nothrow
          |-OMPForDirective 0x1311668 <col:6, col:21>
          | `-CapturedStmt 0x12a5f10 <line:12:6, line:4:11>

```
So, I do not understand what you have said. Can you please clarify? Moving back emitting of taskwait directive back into CodeGen is not much of a problem.
