Underlay Does not List Newly Created View

[annl]

Revit 9.1

We have roof plan where we want to show the canopy on the floor below. Showing floor below plan/ceiling plan gives too much info. Can't change visibility specific to an Underlay as far as I can figure out. So, created new view with the Roof/Canopy as required.

The problem is the Underlay view options for the roof plan doesn't list the new view. I assume to correct this I would then need to create new Roof Plan view. We're too far down the path for that.

Question is then, is there a way for the "Underlay" option to see plan/ceiling views created after the host view was created?

Did I explain that so that it makes sense?

Thank you all. I get a lot out of this forum.

Underlay only displays Levels, views are associated to levels.

Ahhh! Thank you. I should have figured that out.
