Referenced inserted parts into part not saving when main part is saved

Good morning again. I recently upgraded to SW 2020 from 2014 so I may be missing a setting in the options for this, but can't find it.

I have a part (partB) inserted into a part (partA). I open partA and then right click in the model tree on partB and click "Edit in Context", opening partB. I change partB and then go back to partA. partA regenerates and then I save partA. I would be prompted whether or not I wan'ted to save partB as well, but that isn't happening and after I go back to partB, it isn't saved.

Thanks in advance.
