We have a customer that uses A0+ and A0++ paper sizes for drawings that are very long and can be printed by plotters.

These sizes are currently not available on the cloud environment, resulting in an incorrect rendition.

It is possible to add a custom page size on the enterprise version of Meridian:

We would see value in adding the possibility to add custom paper sizes in Meridian Cloud as well.
