TOC title right justifies

I am compiling for ePub. My chapter numbers I have right justified. Apparently this causes the title (ie. the word “Contents”) in the automatically generated TOC to right justify as well. I would like the TOC title to be centered along with the body of the TOC. Is there a way to do this in Scrivener (while retaining my chapters the way they are), or do I have to resort to an external app like Sigil?
