It seems I am unable to understand what exactly you are trying to attain. If you do not set the heading typography for the content in TemplateToaster then it will use it's default typography. Would you please try to describe it more clear.
Yes, I can see I was a bit vague so sorry about that. I am using Visual Composer and, for the most part it works well. But for example, headings are set to align left, and I find that VC is not able to over-ride this. Is there a way of telling TT not to set typography for content?
