Cut a column by slab

[E-Key]

I have a multilevel building in my project and I placed monolithic columns from lowest level to the monolithic slab on the top. Then I placed finish floor onto monolithic structural slab for each level.

Now I need to subtract columns from finish floor and subtract structural slabs from columns. Join Geometry command cuts slab, but I need to cut a column. How to do that with Revit?

Any suggestion will be appreciated.
