assigning asset tags in properties-what does Append mode box do?

[diksha_mishra · Accepted solution]

Append Mode is used to append the new metadata with the existing metadata in fields that contain multiple values. If you do not select this option, the new metadata replaces the existing metadata in the fields.

Do you know if there is any way to have the Append mode option selected by default?
