Hey @zelaphas, at the moment, we don’t have options to customize annual plans (i.e. only for specific tiers, limited number, ect.). This is being discussed over on this thread as well. But I want to assure you that we’re taking the feedback into consideration for possible updates to the feature.
We actually prefer product feedback here in the forum! The Discord is where we encourage creators to chat with each other, but the forum is the best place to ensure Patreon staff see’s your comments. Feel free to leave feedback and suggestions over in this section of the forum.
