Adding Analysis Toolpak and Solver To a Custom Ribbon Tab

[Bearcat Brew]

I have created a custom tab on my ribbon through File > Options > Customize Ribbon and I have populated it most of the way with the Add button. I have added Solver and the Analysis Toolpak (Data Analysis button) addins to Excel and by default, Excel places them at the end of the Data tab on the ribbon in a group called Analysis. Since these are addins, they are not available in any of the lists in the customize ribbon dialog box. I would like to place that group on my custom tab or at a minimum, create a custom group on my custom tab and add Solver and Data Analysis - any ideas? I had used Custom UI years ago and was wondering if it was through that or Ribbon X possibly to do this.
