Is it possible to mass import a note onto a series of records using the import feature? We are on Odoo online, V12, but we expect to move to Odoo.sh later this year.

An example of our use case: We are processing mid-year price increases from our vendors due to the pandemic. It would be helpful if on the same import file with the latest sale price and cost, I could add a column that would allow me to would place a note on all affected records, perhaps to say, "COVID-19 price increase effective Sept. 1, 2020 per email received Aug. 30, 2020." Then the pricing could be updated and the related note added in the same step.

Manually logging notes is fine for a few products, but there could be several dozen or even hundreds of items affected by a change depending on our vendor. For context, our inventory database has almost 200,000 products, so noting some of these nuances regarding changes to product templates would be helpful to our sales team.
