Building mother /daughter company relations

It is possible in Hubspot to create a parent/subsidiary relationship for large companies.

The head office is the mother and the branches are the daughters.

I only see a possibility to link them one by one.
Is there an alternative to do this in bulk from a list function or perhaps from a workflow?

Hello @CD001 thank you for posting in our Community.

I want to share this knowledge base here with more information. Import to associate child and parent companies in bulk, you can add child companies to parent companies in bulk through an import. The parent companies must already exist in your CRM before you import the child companies. Prior to importing, learn more about how to properly set up import files.

I hope this information helps.

Thanks for this workaround. I guess there is no solution within Hubspot for this?
