Is there a way to spread a paragraph over all of a text frame’s columns in InDesign?

I’m laying out a text with lists and headings between them. I used the ‘Text frame options’ to split a page-wide text frame into two columns. Now, it so happens that one of my main headings is too wide to fit in a single column. I think line breaking the column is very ugly, so I’d prefer it if I could instruct this single line (or paragraph) to ignore the column separation and go all the way across the entire text frame. Not dissimilar from what two merged cells in a table would look like.
