Select all edges of analytical floors

Hi all,
I was wondering to know if there’s a way to select all the edges of an analytical floor.
Basically, by default, we have to press tab and click on the edge, then press keep ctrl and press tab to select another edge and so on, at this point we could do analytical adjust and twick the edge horizontal alignment choosing projection floor/slab edge.
I’d like to be able to select an analytical floor or select all of them, then get in Revit the selection of all the edges and twick the horizontal alignment of the multiple selection.
Any ideas?
Thanks in advance
