Disabling Custom Formatting for Title Text

We are trying to introduce a new theme across several report pages to standardize look and feel.  Included in the items that we've configured into our theme json file are font size and type settings for the titles of our visuals.   The issue we are running into has to do with the fact that we've customized the title text for most of our visuals instead of just using the default Title that pops up when you add a new visual.

For example, let's say our theme defines an 18pt font in Calibri for all of our visual titles.   Now, when I come across a visual where I've already adjusted the font from the default Power BI size, I need to click on the Revert to Default link...otherwise the settings from my theme file won't kick in.  The problem here is that clicking on Revert to Default blows away my customized table name (e.g. "My Sales Table") and turns it into something like "Sales by Month and Name", which I don't want... and I really don't want to have my visual titles wiped out each time I import my theme across dozens of report files.

Question:  Is there a way to configure Power BI such that it doesn't automatically create visual titles based on the colums from the query being used?  If I could disable this functionliaty then I'm hoping I would have my custom visual titles overriden each time a theme is imported.
