Couldn't you add the scroll then go in and customize the scroll to show what spell is on the scroll
Unfortunately if you have multiple spell scrolls of one level, they stack. So if I had, say, a scroll of Cure Wounds and a scroll of Bane, I couldn't name them separately. They would either both be labelled as Bane, Cure Wounds, or as 1st level spell scroll.
Perhaps not the answer you're looking for, but, homebrew them. Though I thought I read something about there were plans for it? I could be wrong though.
I give out scrolls fairly regularly as treasure, so I homebrewed a lot of the common spells prior to starting my last campaign and when a not-so-common scroll is found I homebrew it after the session. I have a pretty good library now of homebrewed spell scrolls.
Short term it's a fair amount of work and copy / paste depending on how you decide to homebrew them, but you only have to do it once per spell so in the long run it works out great.
I made this suggestion in the Character Sheet Feedback, but I haven't seen any official movement on it. Though I did see a lot of positive feedback around it. In fact, I just added it to the Zendesk to make sure it was captured there separately and could be voted on.
