Yes, this sounds about right.

Thanks to your work we kind of have a bidirectional conversion between 
packagedb pick/desired state and a SolverTransactionList now, so this 
should be possible.

(Although it should be done when the state of the 'Keep' or 'Current' 
control changes - note that changing this setting clears any manual 
picks currently. [and there's a mechanism to apply the initial state of 
that control initially])
