Trim Paths in Animate CC

All is in the title...
Why in 2020 "Trim paths" is still not available in Animate CC?? It's a basic animation effect, available in after effect but for strange and mysterious reasons unknown in Animate where it's really a nightmare to create similar effect (and spend hours), however Trim path would so have his place in Animate.
I'm an illustrator and animator, I use Animate for 99% of my work and I SO need this option... PLEASE update it!!!!

(and sorry for my uggly english)
