Usermanager print vouchers

Hello, I need your help in printing one-time vouchers from usermanager. I only need to print the codes that I created today and that haven’t been printed before. I can print like this:

/user-manager/user/generate-voucher voucher-template=printable_vouchers.html numbers= [find group=1d_group]

Then it prints all the codes, including those I previously printed.
From winbox you can only print one code at a time…

is there nobody able to respond to this!??
