So I currently have a scroll of find familiar, I was trying to add a scroll of Floating disk but  since  what you actually add is  a scroll  of a particular level and then edit it to have the appropriate name.  So any time I try to add another 1st level scroll it automatically renames it to be find familiar. 

Can scrolls be made a non-stacking item  so that i can have more than 1 type?

Use custom items instead. Or include spells in the item's notes section.

Yeah there's workarounds  but it's still inconvenient  and something I feel ought to be addressed.
