Hide histogram in storage definition on persistent class

Hi All,

is there any way how to hide or remove storage "Histogram" section in the file with persistent class definition, but keep the data both in globals and sql table?
The reason is that we use on-premise version control system and since the data is sensitive, it cannot be uploaded along with the files.

I have already tried "NoExtent" keyword, but that does remove the sql table and just keeps the data only in globals. The only solution I have come up with so far is to remove all the "property" sections from storage in file everytime before committing changes.

I would expect that somekind of a keyword exists that tells the persistent class to keep the definition of the class in storage but not to keep the data locally in file.

Thank you for any advice,
Jan
