Hi Hannes,
I’m sorry that my idea did not work out for you. Unfortunately, I do not have any additional information as to when that feature will be implemented.
If this functionality is a requirement for your intended project, I’d suggest that a third-party developer would be the best way to make this feature happen on a short timeline. ? We maintain a list of developers who work with our plugins on our Knowledgebase here:

Let me know if you have any other questions on this topic!
Thanks,
Jaime
