As far as I know, I don't think you can add a new toolbar. But you can add icon(s) for the macro(s) that you want to run and that icon can be placed in a toolbar.
To add an icon, go to "Tools", "Customize" and to go the "Command" tab. In there look for "Macro" on the left side and select that. Afterwards, 6 icons will be shown and pick the last one (the icon that has a person's face and an arrow). After you placed the icon on a toolbar, you will be prompted with a new window. "Tooltip" is the name of the macro (like the word that show's up bold to tell you what the name of the icon is), "Prompt" is the brief description of the icon, "Macro" is the actual location of the macro. Leave the "Method" as is because that's a Solidworks thing. And you can also add a shortcut key under "Shortcut". After this is all done, simply hit okay and your macro icon is added.
If you want to edit an icon for the macro, you can go to "Tools", "Customize" and to go the "Command" tab and right mouse click on the macro icon and you will get the "Customize Macro Button" window again.
From here, the links work. If you can't get through, email customer service via the web page link and I'll have them send you a copy. (Like how I refer to myself in 3rd person and plural?)
