Rotating a line with an arrowhead?

Hi,

I am using Photoshop 2017.1.1 Release.  I frequently use the Line tool and add arrowheads to either the Start or the End.  After drawing an Arrow in this way, I usually want to (1) move it to another location and/or (2) rotate it to change its orientation while keeping the overall shape and size of the arrow the same.

• I am able to accomplish (1) by using the Path Selection tool to select and then drag my arrow to a new location.  When I do this, I get a message saying "This operation will turn a live shape into a regular path. Continue?".  If I choose to continue, I can drag the arrow wherever I want without changing its size or orientation.
• I cannot figure out how to accomplish (2).  If anyone can tell me how to do this, I would greatly appreciate it.

Thanks in advance,
Paul
