How to make Battleships "Catch Up" to the formation

[anonusername]

I have noticed that in 1.0.9, battleships with the "tight" formation will not actually take any action to maintain a close formation! If I have the lead ship slow to cruising speed, the following ships will drop to match even if they are substantially behind. Is there a way to force the battleships which aren't in the lead to increase speed as needed to "catch up" with the lead ship? This is a serious problem, as it leads to my battleships being excessively spread out and potentially vulnerable to defeat in detail.

On a related note, is it possible to prevent CLs and DDs assigned to the screen mission from hello kittying off and falling behind the BBs? I don't understand how a group of DDs with 10kn+ speed advantage can fall behind a battleship moving at half speed.

If I need to, I drop all the other BBs except the flagship and form a new group, set it to follow. That way they will do so making the necessary speed changes independently.
