Manipulating Sort Order Limitations

Can I ask, where do things stand with Sort Order?

Is there a reason it cannot be manually manipulated more?   If still using JSON, I believe our only options are:

• most_recent: reverse chronological order
• chronological: the order in which the content was published (e.g., Episode 1, Episode 2, etc.)
• most_popular: sort by popularity (based on Roku usage data).

Neither seems very efficient. I thought previously I did it thru the DP Dashboard and there was an option for 'Date Added', so I was changing those accordingly to get the best lineup (I think that was even somewhat buggy).  Are we limited to Chronological (oldest first), Most Recent (newest first), and Popularity?

I know the big channels are a different beast, and have teams of developers, but aside from manually coding every slot how would they be manipulating it?
