Please add the possibility to delete proposals (which are already published) in the sync dialogue of InfraWorks and in the BIM 360 project.
In projects with "obsolete" proposals I would not sync these proposals again and I don't like to have them in my local project again. It would be easier to manage projects with lots of proposals and with proposals which have been used only temporary.
Furthermore this was possible in the management of the old InfraWorks web Projects.
