Hi Pawel, I saw your comment about "reason lost" on Path. I'd recommend voting for the following idea: https://success.salesforce.com/ideaView?id=0873A000000E47LQAS

The dependent field modal is a platform feature that can be used all over salesforce. Once that component is available the path team can use it for this use case. For now users that have dependent fields like reason lost have to update the picklist in the record detail.
