How to copy a feature?

Hello everyone:

So I'm sure this is a pretty basic question:  How do you copy a feature?  I've looked at several other posts, but there must be something I'm missing.

I'm machining some architectural foam reliefs, for example....I've made columns that are attached to a wall surface, and I'd like to copy the columns across the same face without having to constantly set up planes/do mirroring or use patterns.  Overall I'm trying to shorten my workflow, as these designs are getting very ornate.

To figure this out, I made a wall, and attached a box at the base of that wall.  (see attached pic) When I try and "Copy the Feature" by using the Control key, Solidworks insists on copying the box and putting it only on the other side of the wall.  I cannot figure out how to get the newly copied box to stay ont he same side of the wall. .  Anyone have any suggestions?
