Thanks for the request. Let me see if I can clarify something - you are actually looking to both add private sentences to the system, and then also add them into a list or schedule?
Hi マイコー, thanks for the reply, I'm requesting mainly the first part, that is adding existing sentences (the ones I already find via /v1/reibun/search) to a list or schedule by ID, like pressing + in the sentence lookup but in bulk, that alone would cover most of what I need!
