Save action points for travel mode change

[Jagger]

Last night, I had an opportunity to try out the PB demo and I was very impressed.   Looks beautiful, plays well. 

However I had one difficulty with one standard movement operation.  I was trying to manually track remaining action points so I could shift from travel to deployed mode at the end of my move.  I often failed because I wasn't sure how many APs were necessary to move into the last few hexs.  Too often a unit would end its move in travel mode when I wanted them in deployed mode.  

I noticed in one of the menus an option to "save movement costs".  Apparently, it ensures some action points are not spent so that the unit can fire at the end of the adjusted move.   I looked for something similar which would save action points to ensure the ability to change from travel to deployed mode.   I couldn't find anything like that.  Am I just missing it or is it not there?
