Activity Table Timestamp in Milliseconds


I have a use-case where events can happen super fast.
Hence, I build an activity table with a Millisecond Timestamp.
When I read it in via file upload, it detects the Milliseconds with the format ‘yyyy-mm-dd HH:mm:ss.SSS’.
But after loading it does not show the miliseconds in the respective timestamp column, only with seconds.
Do you support Milliseconds for the timestamp column?
Do you have a workaround for proper ordering, when Sorting column would not work?

I would appreciate any help.
