Randomizing fossil IVs doesn't seem to default to at least 3 best IVs.
Mew and Zacian/Zama work with randomizing 3 best IVs (both batch editing or clicking "Randomize IVs").
Is there a way to get the fossils to also default to 3 best IVs in order to make randomizing easier and keep it legal? AFAIK fossils must come with at least 3 perfect IVs.
