I am using Visio 2013 with the UML Sequence stencil objects. When I add an Object or an Actor lifeline to the canvas I can grab it at the bottom by the yellow diamond symbol and extend it to make it longer.
However passed a certain length the lifeline no longer adds connection points to itself thus being completely useless. I can manually add control points to it by choosing the connector point tool and control clicking on it. But this method is extremely non practical as it does not align the points on the line and it is very hard to have them align vertically over several lifelines.
Is there a way to make Visio automatically add more of the control points?

You can create a custom stencil, drag the fixed shape over to the stencil and select 'Edit Master'.
Due to link rot potential, I'm copying verbatim from the following:
Edit a Master Shape
When you need a specific shape and none are exactly right, you can pick a shape that’s pretty close, make a copy in your own stencil, and customize your copy of the shape. The customized shape is available in any diagram you make.
Copy the master shape to a custom stencil, such as your Favorites stencil, the Document Stencil, or a new stencil. For information about custom stencils, see Create, save, and share custom stencils.
In your custom stencil, right-click the master shape and click Edit Master > Edit Master Shape. A new window opens with the shape ready to edit.
Make changes to the master shape. For example, use the data tools to create Shape Data fields, the Shape Styles tools on the Home tab, and the Shape Design tools on the Developer tab to make the changes you want. When you’re done, close the window. Visio asks whether you want to update the shape. Click Yes to save the changes.
This will create a new shape with your additional connection points that you can reuse in the document.
Complex master shapes are usually made up of many small, simple shapes that are grouped together. You can edit those small, simple shapes, for example by changing the color or size of one or more, by following the next procedure.
Create, save, and share custom stencils
You can create a new stencil to hold shapes that you use often and want to find quickly. After you have created your new stencil, you can then save it to reuse later or share it with other people.
Create a new custom stencil
To open your new custom stencil in another drawing, in the Shapes window, click More Shapes, point to My Shapes, and click the stencil name.
Add shapes to a custom stencil
If the stencil title bar has the icon A red asterisk indicates that a stencil is editable. (asterisk), you can edit the stencil by adding, deleting, and modifying shapes.
