As it is quite time consuming to go over all the problems (errors/warnings) out of import project to resolve them, having an option to export the problems to an output file would be really handy for users who deal with bringing huge chucks of data into Fusion Lifecycle (FLC).
As per my observation most of users would like to update the source (data in excel file) than the data in import project (This makes the data in both the import project and input excel file consistent) to bring it back into FLC.
