I have an xs module that attaches some magic to a variable using Magic Virtual Tables with a type of '~'. Reference Re: Marking an array as already seen ('~'magic virtual table)

How do I preserve other user defined magic?

It says in perlguts,
If sv is not already magical, Perl uses the SvUPGRADE macro to set the SVt_PVMG flag for the sv. Perl then continues by adding it to the beginning of the linked list of magical features. Any prior entry of the same type of magic is deleted. Note that this can be overridden, and multiple instances of the same type of magic can be associated with an SV

My question is, how to override it? I've looked throuh much of the source and googled like hell but cannot find the answer. Any help would be appreciated.
