Hey everyone,

I have a lot of sub-assemblies in my main assembly, that I can't pattern, they are very scattered. And when I imported them by default they were not set as flexible. And now I have to go and click on each sub-assembly and make it flexible one by one, because when I select all of them, the option to make it flexible doesn't show up, and when i go to properties of all of them together, the option for making sub assemblies flexible is grayed out. any other options ? 

I am using SW 2019 SP3.
