Connecting line and arrows?

Here is the closest thing that I could find and is exactly what I want to do, but you can't add arrows to the lines ....  Under the shapes there are options for callouts at the bottom. if you make the callout itself transparent, then the line is actually three lines connected that can be moved as needed. This is not the purpose for this feature.. but the line is what I am looking for ... need arrows and endings... it is basically a single line with a couple elbows that can be manipulated. Strange that I am the only one looking for something like this (shrug). See the attachments.
