I would like to create a new LCIA method by merging two existing LCIA methods. For example, I would like to merge TRACI2.1 and CML methods in one LCIA method. The copy and paste function does not work when we create a new LCIA method and it is cumbersome to add 100s of flows and create the LCIA method. So I end up running the same product system twice to calculate results according to TRACI and CML. If it is possible to merge existing LCIA methods to create a new one, then it will save processing time. Is it possible to do this in openLCA?
