I have a block list. I would like to set the initial allowed block types to be one of five. Once they add the first block type to the list, I would like to restrict the subsequent block types to be the same block type. I would also like to change the minimum and maximum number based upon the first added block type.
Is there a programmatic way to override the block list configuration for a specific block list?
