Multiple receiver-everybody should get their own document

Hello, we decided that we want to send our documents to our costumers by E-mail and when we tried to send 1 document to multiple persons it was in order. Is it possible that multiple people get their own document ? It should be like in an E-mail, when you put 5 people in CC or BCC everybody gets their own email and everybody has their own document. But when you put multiple signers they get that in order and the second receiver can see the already filled Fields from the first person. That shouldnt be. I would be really thankfull if someone could help me out.
