Precision Endcaps???

I’m late to the party, but I’m watching the Dankpods collab from March 24. Saw his green endcap, and got so excited! We have the endcaps 3-pack, and the Floatplane set (I have both of these, along with two regular sets (yes they all are used, it’s significantly easier to have sets dedicated to an area instead of trying to make my ADHD and object permanence work)). Anyway, what’s the likelihood of getting more endcap multipacks??? I’d love to see some additional colors from black and orange (and blue).
