Question about Queue

For example, the command Copy QUEUE=MyQueue will copy selected files using the queue MyQueue. You could then configure a button or hotkey to copy using your named queue when a particular key was held down (e.g. Shift) - that way you could force the queue to be used when desired, even if Opus would ordinarily not queue the operation.

So if I have started some operation by Copy QUEUE=MyQueue
then I want to add to the queue
Select ALL
then
GetSizes HASH=md5

how I need to do to achieve such result?

I fear QUEUE is only an argument for Copy and can't be used anywhere else.

even if Opus would ordinarily not queue the operation.
