I am creating a class diagram in Microsoft Visio 2010 for a Java Program. I would like to set an operation's visibility as being package/default, but that is not an option. The only choices are public, protected, or private.

I realize this isn't a typical visibility option for most programming languages, so Visio most likely doesn't support it. However, is there a way that I can define a custom visibility option for my diagram?
Edit:
BobRodes got it right. If anyone is interested in how to do this, I will explain below. Please note that I am using Visio 2010. If you have a different version, the process might be slightly different.
- Click on the part of the diagram that you want to edit. In my case, I needed to change the visibility of the operations, so I clicked on that section twice. Once to select the class, and again to select the operation section.
- Right click on the selected section, and click 'Show ShapeSheet'. This should open a separate dialog with a bunch of properties you can mess with.
- Scroll down to the section entitled 'Protection', and change the value of 'LockTextEdit' to 0. You may now close the ShapeSheet dialog.
- With the same section still selected, click on 'Text' at the top of the page. This can be found on the Ribbon under Home->Tools.
- This will put the selected section into edit mode and you may what text is displayed.
** Important ** If you make any changes to the shape properties such as adding/changing a method or variable, this will rewrite the shape and remove any custom changes that you have made.
