Adding foods without adding to diary

Hello,
I'm using the app on my iPad/Android/Desktop. When I'm in a store and want to add something via barcode that is not something I'm going to eat immediate, rather (for example), I had it at home and don't have the original package.

It appears to me the only way to add something is to add it and then delete it off the diary. The new food add, doesn't allow for a new bar code scan rather it is a pure manual fill, much like the autofill if a barcode was scanned.

It is nice that I can scan something and see if it goes over the present set of carbs or whatever, but I'm looking to add things that I'm sure aren't in your dB without adding it to my day.

thanks
