How to update database without overwriting selected organization

InfluxDB 2
1

I’m creating a testbench database for my company which will contain the same data as our production database. However, the testbench database will have a few organizations which are not in our production database. I’ll need to regularly add data from our production db to the testbench db in order to properly test things. I normally use the restore command with Influx CLI and from what I understand this will overwrite all existing data in your current db. Can anyone recommend a way to update the organizations in my testbench db with their production data while keeping the data safe for the organizations in the testbench db which are not in the production db?
