Changing dimension layers?

[dsauder]

I'm afraid I've discovered another limitation of Pro.

I'm trying to make prints of my floorplan on a layout. I have modeled on my plan all of the trees on our lot, and I have dimensions to all of them as well. On my prints, I do not want to include the trees or their dimensions. I can turn the "Plants" layer off so the trees don't show, but can't get the dimensions turned off without losing all dimensions.

Is there a way to create new layers? Or to switch the layer a particular item is on? Or a way in the layout file to manually remove certain dimensions?
