When You make One Parcel and send through courier, it will generate only one Docket Number from the Courier service, and you cannot put the same courier details on all seven transactions, your Paisapay Payment will be Held.
Try talking to buyer and inform him that according to rules of paisapay that is not possible and you will ship the items the same day, so he will receive it all together only difference will be different packages.
I hope this helps.
Thanks
