[Expand stroke with arrowheads]

I found interesting thing with expanding stroke with arrowheads.
If I trying to expand stroke of unclosed path with center alignment - everything is okay, but when I using inside or outside stroke alignment, shape is losing arrowheads. It's a problem because unclosed path with different stroke alignment looks same whatever is it center or inside/outside. 

This problem same for both Designer versions PC or iPad.

[Macros for Batch processing?]

Where I can find macros in Batch processing? I find guide in Help section, but I can’t find any macro option in batch processing. Also batch help page looks like a Windows or Mac version...
