Bulk Add Items on mobile device

I want to allow users to add multiple entries to a list of rather complex items. The user needs to pick

  • color
  • number
  • date
  • dropdown
  • dropdown
  • (later a optional picture)

putting this in a single page form on a mobile device is quite straightforward, but users will eventually add multiple items quickly. Going back and forth between the list and the form seems suboptimal, but I am unsure how to layout a batch add.
