We'll get this reviewed as soon as possible.

I've had a chance to test this out, and I can only get it to compile if I do not make the changes you're adding to the BlockGridElementData (line 613) in the Model..cs file 🤔

It gives me the following error: Property or indexer 'BlockGridElementData.Data' cannot be assigned to -- it is read only

Perhaps it is not needed to change this method? 🤔
