Adding properties to a relationship from Bloom editing interface?

Hello all,

I am trying to propose a way to directly use Bloom to enrich an enterprise knowledge graph.
There is almost all the needed actions for edition but I am not able from Bloom to add a property to a node or a relationships. I can only edit the value if the property already exist.

For the nodes there is a workaround by duplicating an existing one but not for the relationships.

Has anyone found a way to do so?

Another way that could be ok is if in a search phrase there is a way to modify a link but so far I can only have a RETURN clause working. I suppose this is the way it is intented to.

Thanks in advance for your help.

Kind regards,

St├ęphane
