Free Scroll of wisdom uses in camp

Unsure if this is intentional or not.

Noticed this while messing around with the scroll of wisdom's in camp before having the stranger available. If you buy a single scroll from Una in camp and have a inventory full of unidentified items holding shift and using that single scroll I was able to use it on each item as long as I held onto the shift button.

I have tested this out while outside of the camp and it does use the last scroll on a single item, it does not appear like it takes any additional money out when doing this in the camp.

Is it taking scrolls from your stash when doing this?

So I did test it out, it does look like it is pulling from the stash itself, so maybe not a exploit, but I did try to do the same thing but in inventory, Leaving only 1 scroll on my person and see if it lets me use it on all my items, but only used once.

Still can be useful if trying to sell items to the store and dont have the hooded one unlocked yet
