No 737 MAX official orders breakdown?
 

I've been looking for an official Boeing 737 MAX orders breakdown for each of the models (i.e. 737 MAX 7, 8 and 9) but it seems that it doesn't exist! Can anyone help? I've had a look at the following links but since they're unofficial they're bound out of date while the order book is growing:

https://en.wikipedia.org/wiki/List_o...737_MAX_orders

Airbus A320neo vs Boeing 737MAX - Orders and Commitments

For info, below are the official Boeing sites I've had a look at:

737 MAX Airplane | Boeing Commercial Airplanes

The Boeing Company

Any help will be greatly appreciated!
