We are experiencing an issue with adding PowerPoint files to an SDL Project. 

On one machine we simply can't create an SDL project with this PPT. On another we can but we are unable to clean the file due to a "Duplicate column names( are not allowed" error. Which probably has to do with some embedded Excel tables in the PowerPoint.
If we find and replace the column name in the translation, we do manage to save it as PPT again. However this not viable solution as quite labor intensive and error prone.

Is there a way to disable this check? Frankly we don't care if there are duplicate column names if that is how the author constructed their tables.
