Split mail to multiple recipients by postfix to single-recipient-mails before delivering to smarthost

[freisei]

Hi List,

Is it possible to split all mails to multiple recipients into single 
mails with only one recipient before delivering to my smarthost?

I tried to get answer from https://www.postfix.org/postconf.5.html but i 
think there must be combined some of the configuration-options.
