Easy way to select parent and child task in a plan

I am looking for the easiest way to move a parent (with all of its children) to other iterations in a plan.  (similar experience to when this is done in Microsoft Project).
In the example below I would like to select "validate loan" and all the children so I can move it to another iteration.
Currently (V 4.0.4 of RTC ) seems to require me to first expand all the levels, then select the children individually. This is very tedious for stories that have lots of children and is also error prone as users expect behavior similar to MSP for this action. (Which is select the parent and all "sub-work" come along for the ride).
Is there a way to handle this usability concern for customers and make it easier?
