CONNECT U16 - Custom Ribbon Panel - Tool Button Alignment

I have been working on & off for a while now to create a custom Workflow ribbon for our CONNECT environment. I do not like all the tabs and the need to switch from one tab to another. I've also created/modified some of tool panels. As you can see in the screenshot I have the Attributes panel so that the standard drop down fields are available, but I also added the button to show the dialog for the various Level Filters. This allows us to change the active level filter from this list (I know you can drop the active level list and select the filter there, but that causes the drop down to collapse & you need to click it again to access the levels once again). As you can see the active level drop down is on top with the line style & line weight drop downs directly underneath. The color, priority & transparency buttons are pushed to the outside edge of the active level  drop down. Looking at the Help documentation there is mention of margins (for tools) and center alignment (for panels). There is a panel section as well that allows you to define the type of panel and alignment of the buttons within the panel.

I do not see any of the alignment options or the panel type options anywhere and the margin field is greyed out.

Is there a way to reorganize the tool buttons within panels on the ribbon?
