Given I'm at xmr conference 
and want to go on xmr spending spree
Then I should have already a few utxos ready. 

Right now I usually have only one utxo and after first purchase I have to wait insane amount of time to get utxo from previous tx spendable. 

Can we get this nice feature where I decide in how many coins I want my change back? Ideally, optionally specifying each coin's value?
