This is one reason why every piano has a sustain pedal - the one on the right. Press it when you play the first note in the bar, and keep it down until you play the first note in the next bar. Repeat as needed.
Since all the notes in each bar belong to the same harmony (chord) it will sound good, it will flow, and give you chance to move your hand from the lower note to the dyad above.
If you're lucky enough to have a piano with a middle pedal that is not just a quiet practice pedal, but a sostenuto pedal, you could use that instead. It works nearly the same, except it holds onto only the note played while it's pressed - others will be played normally.
The sostenuto pedal is common on pianos on the left of the Atlantic, rare on the right.
