Hey There,
One of the things that Inventor is excelling from other products, it is its Content Center and all the adding parts automation.
I just moved from Inventor to Fusion 360, and I must say, I like it. But I'm quite surprised. Everything about Fusion 360 is more new, easy and make sense, except when you need to add a part (a Screw, a Bolt etc....) from the library. This is where Fusion 360 is falling short!
I hope, somewhere in the Near future you will improve this functionality and make it like it's in the Inventor's Content Center.
Unfortunately, right now I'm juggling between Inventor and Fusion 360 because of that 😞
Cheers / Ben
