Project/ shopping cost totalling

Ok so I appreciate this is something that the dev probably isn’t keen on implementing, but has any one managed a shortcut that can be used to create a total cost in a list? Perhaps a shopping list could have the cost in the notes and then an ios shortcut could total selected items?

We have a wish list, a Christmas list and also a building project. All of these have prices and it would be great to see a total cost involved. The only app I’ve found that does this is listonic but it doesn’t really integrate with my workflow.

Any help appreciated.
