Currently, Batch Forge automatically selects an Ubuntu 20.04 image when creating an Azure Batch pool. This is EOL next year and furthermore there are many use cases where you need to select a different image type (e.g. accelerated computing). It would be helpful to be able to select any virtual machine image that can be selected via the interface, instead of resorting to manually setting up a node pool.
