Pack and play question!!

So my aunt is giving me her pack and play that she bought for her grandson and he never used it. But it’s just a basic one without a bassinet or changing table connected to it. It was like $30 at Walmart.

I wanna use it for my baby to sleep in my room till theyre older but I need something less deep because this one is meant for older babies.

Does anyone know if I can get some kind of bassinet attachment for it? I don’t want to buy a whole new one for like $100 if I’m getting one for free. But I want to be able to use it for a newborn as well as when the baby gets older.
