Is there any other way to create 'shape-key's and also rename for multiple selections at one go?

hi…

when i press Alt (copy to selected) on + symbol,
under Shape keys column in data props, its not working !
ie its applying only for actively selected one.

is there any other way to create 'shape-key’s
and also rename (same shape-key name)
for multiple selections at one go ?
