Microstation Application pulldown edit?

I want to alter the Microstation Application Pull down to load the Bentley Inroads ,  my users accidentally pic software we do not own and we get 

nailed for over usage fees. We even have a third party software to help us control this  but some how users still manage to hit something we dont own

I want to remove SITE, SITE SUITE, BRIDGE, RAIL  

I did manage to local the dgnlib that seems to control this however the option to edit is grayed out 

I have considered making my own custom menu with the MDL load key int and remove the CFG from all pc

any tips on this would be great
