How do I change room item information?

I want to change the information about one item, how do I do that?

Let's say you need to specify that one item needs a crate, is damaged, is valuable or you just want to add a note to it. Tap on the item you want to adjust in the template. You will be prompt on the same page as when adding an item through advanced add where you can add all the details. 

I want to change the information about more than one item, how do I do that?

Let's say you need to specify that 2 or more items need a crate, are damaged or you want to add a note to them. Once the template is added, go to the Inventory page, select the items you need to modify (tick the empty box on the left side of the item) and tap the Wrench icon (it's below the filter button). Here you can change the MOT, room, destination, crate, valuable and disassembly info. Volume can't be adjusted this way, you have selected multiple items at this point.
