Hi @klm46,

I think what you need is a dedicated [scripted field](https://www.elastic.co/guide/en/kibana/current/scripted-fields.html) that would extract this portion of another field for you. Similar to what has been done here: [Scripted field for Matching Substring](https://discuss.elastic.co/t/scripted-field-for-matching-substring/147013/2)
