That is correct.
The only method you might have to do that in 2.2 would be to use the low level goldsh prompt to directly modify the ReservationAllocation values:
gold> ReservationAllocation Modify Reservation==2 Id==20 Amount=100
Reservation Id Account Amount
----------- -- ------- ------
2 20 3 100
Successfully modified 1 ReservationAllocations
> Question background:

A future version of Gold will have a greserve --modify option that will allow you to modify an existing reservation with new allocations, etc.
I may eventually backport this to Gold 2.2 as well.
