Currently, when exporting the Leap Bridge Steel (LBS) to perform substructure analysis, you can only export one live load vehicle at a time. Our project has two separate vehicles to be analyzed. One workaround is to export the loads, close the file and then export the second live load and add to the previous results. For situations like this, it would be a lot easier to be able to toggle or select multiple live loads similar to how the dead loads are exported.
