Forgive my poor first shot at a screencast.
No worries. It worked 😉
Imported assemblies such as the potentiometer are design files without a design history or timeline. That is intentional as this allows "things" to be fixed without cluttering the timeline with unnecessary features.
If the imported part is only comprised of bodies all located in the top bodies folder, then you can go ahead, save the design as is, and use/insert it in other designs.
If that assembly consists of components, some work needs to be done. By default, all components in a Fusion 360 design are floating. In a DM design (Direct Modeling, so no timeline) by default components cannot be dragged around in the viewport (but there's an option to enable that) so it appears they are all assembled (not floating), but that isn't the case. If you insert such a design into another design that does have a timeline (new designs by default do have a timeline) then there you can drag all these components around, or you create an assembly joint and only that particular component is joined, but not the rest of the imported assembly.
If the imported assembly is a static assembly, so no moving parts (that would apply, for example to the potentiometer) in that assembly I would create a rigid group joint at the top level (the root of the browser) including all component origins including the top-level origin to lock them onto place.
Then when you use an assembly joint the entire imported assembly will be joined as expected.
@g-andresen the above should answer your question as well I believe.
