Decimal precision of change history?
 

I'm working on shared workbook, and extensively use tracking changes.
I have a problem with decimal precision of reported changes if cell
format is Number:

If I have a cell with format General, and change it from 1.123456 to
1.123457, then change history (tool tip when I hover the cell with
blue triangle) says "changed cell from 1.123456 to 1.123457". This
is what I (and customers) need. But when cell format is Number
(with 6 decimal places), tool tip says "changed cell from 1.12 to
1.12". I want to report it in the same way - "from 1.123456 to
1.123457". I have tried a few things (like changing number of
decimal places in Format Style), searched Google - no answer found.

Can you please provide me with a solution - how to adjust decimal
places in changes reported for numeric cells?
