Walls Hiding Architectural Block

[nowxlr8]

I use a belled pile rather than the normal pier that supports the grade beam. I had to create my own by merging a slab and a cone. The only option to combine these two objects this way gives me an architectural block.

 

 

When I then put that in my plan, it shows up like this:

 

 

There's no option to bring it to the front or anything like that since it's an architectural block. If it shows up like this, I can't use it for the plan. Ideally I want it to show up like this:

 

The way I got it to show up on the third picture is that I unmade the architectural block. It seems silly to put them all in and then un-block them all afterwards.Is there a better way I should be making this pile or way to achieve this?
