Dynamic cells for aesthetics columns


We need to model the following columns but the templates only give the option to model circular, rectangular (chamfer, fillet or bevel) and oval, with no option to include these aesthetics elements in the corners of the column.

Would it be possible to create a dynamic cell with this section to be applied to each column that could be adjusted afterwards to its length (elevation constraints with DTM) with no need to create a cell for each column? We have a lot of structures in the project and, hence, lots of columns.

Thank you.
