I have the same problem with this post, but don't see any response.
Q: Can you assign the cell view to specific category when you create it?
it's really annoying that you have to manually modify the category to add the cell view.
I am using IC618.
The same problem came up 18 years ago, https://comp.cad.cadence.narkive.com/QgTHASuJ/adding-cells-to-category-when-creating-them . Hope there is a solution now.
Thanks.
