As of right now, you can either delete All cards from integration, all integrated assets, the integration entirely, or individually delete HaloPSA cards. It would be great if this was more fleshed out to include options such as:
Only delete HaloPSA assets associated with a specific asset group
Only delete HaloPSA assets associated with a specific client
Delete HaloPSA assets that don't have manually added data
Having a DELETE request function through the API for cards
