[Solved] "updating schematic sheets" and returning some symbol properties to default

[zd2020]

Hello all,
Let's say there are two different footprint at a component in the schematic library. Footprint_1 and footprint_2. And let's say Footprint_1 is the default but i'm using the footprint_2 in the schematic. When i make "update schematic sheets", the footprint returns to default value. Similarly comment and description values are turning to default values. Is there any way to update the schematics with protecting these values?
Thank you.

Hello all again,
I was updating the components from SCH Library, right click and "Update schematic sheets" command. But i found that better command (Tools + Update from Libraries command) in the schematic. It is creating ECO reports and i am deciding which will update which not.
Thanks.
