Create a copy of an inventory item

A minor request: I create a set of inventory items for each of the tours I run. Each tour may have up to six different items, differently priced according to the accommodation type included. They follow a similar format for the item names and descriptions, so it would save me a lot of time to be able to make a duplicate copy of an item then make minor edits to the new copy, in the same way that I can easily make a copy of an existing sales invoice.

As it is, I have either to re-type each item from scratch, or laboriously copy-and-paste the individual fields one at a time before editing them.

I’m sure I can’t be the only one doing this.
