Create new flows in bulk

Question

I see Chapter 22.3 openLCA and Excel allows copy-pasting inventory from excel to openLCA. To use that I have 150+ streams across multiple processes. Several of these streams would require creating new flow. Creating a flow one at a time would be very time consuming. Is there a way to bulk create multiple new flows?

I created the jython code in Excel by "textjoin" of strings. I copy-pasted this in openLCA's jython window. Once the syntax issues were resolved, it worked like a charm.

But it doesn't recognize whether the flow stream already exists. So, it creates duplicates.  I didn't see anything in Jython manual regarding how to check whether a flow, process or system already exist. Any thoughts?
