no, this is unfortunately not possible.
As this is a feature that would have to be implemented in Masterportal itself, we do not think that this is coming soon.
We do recognize the need though, so thank you very much for your message.
We are thinking about different ways of re-enabling at least some of the functionality that was given by this.
A note to anyone else coming across this:
Feel free to either the original message or this response, so we know whether this is a much-needed feature!
