Patreon automation

Is there a way to simplify the patron’s life?
Every month I create a different post for each type of tier or Patreon (because each patron, depending on how many months it supports me, receives a different reward).

Instead, it would be possible to make a single post per month, with monthly rewards, a single button with the words “Click to receive your reward”, and then through some checks, the script manages to assign the right file to the patron. Would it be possible?

Such a format does not exist at Patreon but it could be done by extensive custom coding on a WP site or a custom app using the api. Technically you would use an interface to make a ‘big post’ which would have different sections/attachments for each tier, and then that could create different posts for each tier by using the values entered in the ‘big post’ maker for each tier.
