Import tags for customers

Hello, I am looking for a possibility to import tags for customers. I have an excel-file with CUST-xxxxx and the tags. Is there any direct way?

Example:
CUST-10001 have tags “tag1” and “tag2”
CUST-10002 have tags “tag1” and “tag3”

I could define the tags before als tags if necessary (only about 5 tags).

Easiest way, I did an import in tabCustomer in field _user_tags.

You could try importing with using a Naming series as part of your ID ?https://erpnext.org/docs/user/manual/en/setting-up/settings/naming-series
