When zapping to a drop down box or radio button (single select field) is it possible to ONLY update the field if the target field is blank (i.e. not selected)?
For example, I want an action to update CUSTOMER SOURCE, but only if the CUSTOMER SOURCE is not set in the target field (action).
If CUSTOMER SOURCE in the destination app has a field, it should not override this field, but the zap should update/add the other fields in the zap.
My current zap overrides (changes) the previous CUSTOMER SOURCE field.
I’m zapping from Webflow to ActiveCampaign.
