Endpoint /subscriber/setCustomFields (more than one field per call)

Goal: set more CUFs via API We have API for Create and Update user: based on what i'm understanding, these 2 endpoints only work on system fields, they don't allow to value any custom fields, right? For custom fields we can use the following PUT methods: /subscriber/set-user-field /subscriber/set-user-field-by-name but they seem to work for only one field. It would be nice to massively set values for several custom fields by making one call. You can see this endPoint from ManyChat to understand better my request: https://api.manychat.com/swagger#/Subscriber/4d01076149250e9e47f3b8aa7dc53baa Thanks!
