Waiting for Customer update

[Jim]

So strange one, we have a sub status of waiting for customer that will set the status to on hold and when the customer updates it will flip back to open.

I have a workflow where I want it to sit on hold until the customer responds within an expiry period, 

 

Why can't I choose status on hold to set my sub status of waiting for customer update? I can't use the 'place on hold' either as it won't allow me to set the sub status for it
