Hello Alex,
Thank you for your patience.
The issue you reported was passed to our Development Team and is now processed by them in a separate system.

Right now I have to close the ticket, but please note that it only means the issue you reported cannot be resolved by means of Support Team and needs a deep involvement of Development Team.
Please note that you will be able to contact us within 14 days after the ticket is closed.
Best regards,
