Load Custom Tool Palette First

So what I thought would be a simple problem with a simple solution is now causing some headaches. I have created a custom office standards tool palette for the users, and it is properly loaded on all the machines. The issue is that when the 'Tools' button on the ribbon is pressed, it loads to the 'design tools' palette by default. Most user here have the habit of closing the tool menu after use, and reopening it from the menu - which defaults back to the design tools palette instead of the office standards... which is frustrating when jumping back and forth constantly. I assumed there was an easy way to tell them to set the 'standards' as the default, but I can't seem to find this property anywhere. Ideas? Thanks.
