Change Primary and Minor revision to Primary

Hello, 

We have on the cloud some project wich was save using Primary and Minor revision scheme. ex. "A.1".

Right now we change revivon naming to only USING Primary revision ex. "1" - it's work for new content but old we still see "A.1".

I try reload Cache, update atrributes but we still see "A.1". 
It's possible add for all the objects on the platform New naming rules?
