Adding a field to the createMailingList API call

Hi, I wanted to know if it's possible to add a field to the API call to create a mailingList so it can be sorted directly inside a folder.
Tell me if you already have a solution for that because it's only possible to do it manually right now and that could be really helpful to have that feature. because if we create a MailingList with the API, having to move it manually is inconvenient.
