Sure in the practice problems just launch him below the lowest aircraft headed over SQS. In the current evals there may or may not (wink wink) be these two situations.You just launch him below the lowest guy on the board.
An aircraft is enroute over SQS headed to HLI or UJM when you get the call and your VVBA wants to go south. Depending on where the enroute aircraft is if you release VVBA below the enroute aircraft you get an error for over restricting. (You have to use the fixes to determine if the aircraft is clear of KGWO departure )
A VVBA calls immediately after a departure. Depending on how quick you were to answer the call you have to wait for the aircraft to vacate the MIFR or MEA (and add an airway into the route) or vacate 030. (Can’t give an EFC you have to wait on the phone as you stare down the data block)
These situations are not rocket science and most should be able to handle them but they are more complex than what you see in practice problems.
