Replace font in Document Designer in complete document

Summary:

We need to replace the font in a huge document created in Document Designer with a different font. It is not sufficient to change the font on top level as it seems to be configured in each an every element (text, table cell, …). Clicking through all elements to change the font to be used will be huge effort.

Is there any way to change the font globally to a different font?

In the deprecated Document Engine there was a download of the XML possible where we could exchange the font values globally and re-upload it to CPQ. This seems not to be possible in Document Designer.
