How to show more properties in Part - Changes tab!!

Hi,

How can I show more properties (columns) in the Part - Changes tab.??

Example: ECO/MCO... creation date

I have tried modifying

C:\Program Files (x86)\Aras\Innovator\Innovator\Client\Solutions\PLM\xml\ChangesGrid.xml

and if I modify (add a header) in usps tracking

 C:\Program Files (x86)\Aras\Innovator\Innovator\Client\Solutions\PLM\scripts\Changes\Changes.html 

the new column becomes visible on the part changes tab, but all changes are gone/ not visible
If I remove the added header = my changes are visible again. showbox

 Anyone knows how to fix this?
