No, I did that already. I practice slow and methodically. I keep a measure-by-measure logbook of progress. Muscle memory established. I can then play expressively from memory.
But eventually I'll move on to the next piece, and wind up forgetting to re-visit the other one for a few weeks or months. Gone!!

Maybe adapt your practice to the forgetting curve, revisit a piece the next day, then in 3 days, then in 7 days, then in 2 weeks, then 1 month, then 3 months, etc. If ever you mess up the piece, then it's back to 1 day.
