The PieSync rules allow you to create filters and actions. Here you can select the label/group as a filter or action.
|When working with the new Google UI, “labels” are the same as the Piesync “groups” filter. Below an example on how to sync groups/labels with tag in KW Command.|
In some other apps, you can directly map tags both ways. For example, in this sync with Liondesk CRM, the tags can be directly mapped as part of the field mapping.
