if you can get the private key (don't know much about Phoenix or Sparrow) you could presumably import it into Core and use it as another input in a tx with other amounts in the wallet - whether it's worth it economically is another thing, but it could be used as an input and not become another dust UTXO in that seemingly ever growing graveyard of unspendable outputs.
