Multi Level Tags update via API

Hi Team,

We are using the policy updator api to update tags.

I have attached the sample json to this post.

Currently, if I don't pass either of the tags to the json field, API is removing the tag completely in Expensify.

Is there a way we can run the same in kind of append mode so that if we don't pass the tags, the previously setup tag remains as is?

Kindly let me know.
