Variant analysis

Hello Realtime LCA

I have a question regarding construction comparisons.
Are there any methods to be able to compare the constructions with each other without having to create a completely new project and find the individual constructions under project breakdown, where the total co2 is listed. I would like to create a construction library where I can compare them with each other in terms of for the different phases, just as you can in LCAbyg and other platforms.
