Formatting Problem with Summation Symbol

I often write short derivations in a single cell with a statement on each 
line and sometimes Print statements interspersed as commentary. This gives 
one input cell and multiple output cells. Then one can select all the output 
cells and double-click to hide the input cell. However, sometimes it is a 
bit inconvenient to select all the output cells so I would like to display 
them as lines in a  Column instead. Then there would be only one output cell 
to select. However, it is difficult to obtain the same formatting in Column 
as one obtains in output cells.

Here is an example:

p[x] == Sum[a[n] x^n, {n, 0, N}] // TraditionalForm

Now I try to display the same statement as part of a Column. (Usually one 
would have more entries but here I just simplify it to one entry.)

Style[Column[{p[x] == Sum[a[n] x^n, {n, 0, N}]}],
  "Output"] // TraditionalForm

This does not look like the ordinary "Output" formatting. I can improve the 
limits positioning by using:

Style[Column[{p[x] == Sum[a[n] x^n, {n, 0, N}]}], "Output",
  UnderoverscriptBoxOptions -> {LimitsPositioning ->
     False}] // TraditionalForm

This still does not look like normal "Output" because the Sigma is too 
small. I can make the Sigma larger by using:

Style[Column[{p[x] == Sum[a[n] x^n, {n, 0, N}]}], "Output",
  UnderoverscriptBoxOptions -> {LimitsPositioning -> False},
  SpanMinSize -> 2] // TraditionalForm

But now the brackets are too large. Is there a method to use a Column 
expression and have each line look like regular Output formatting?
