Can't you just grab a bigger cluster/bunch and remove N bananas so it has the amount you want? Or remove 3 from the bunch that has five so two 5+2 clusters? Feels like I'm missing something obvious here.

Yes, because Instacart is ordering for delivery :)

Oh yeah, of course, guess I kind of forgot the overall context, and I was thinking in-person shopping... Thanks! :)

Yes, once I can put in the delivery details something like '7 medium size bananas, with no bruising, varying in ripeness from almost ready to still slightly green' and let a robot at the other end sort it out I'll be happy.
