    I have a .7z archive that I manage using 7zFM (File Manager) and I can easily add objects to this archive. However the objects in the archive are encrypted with AES like I want them to be, but when I add something new I cannot seem to add encryption to that file within the archive unless I decrypt the entire archive, then recrypt it.

    Is there an easy way to add encryption, or perhaps remove encryption, of specific files within a .7z archive?

    If you don't see 7-Zip on the context menu, you may have the 32-bit version of 7-Zip installed on a 64-bit version of Windows. Install the 64-bit version of 7-Zip to add the missing context menu item. Source

    If you already have the archive open in 7-Zip, make sure to close it before adding the file; otherwise, the archive will be "in use" and can't be overwritten.
