Merging View Title Types into One Family

We have several different View Title Families saved, however, each family only includes one type. The families were created by editing and doing a "Save As" on the previous family and then re-naming the family to reflect what that view title was trying to accomplish.

I'm attempting to clean up our project template and I would like to combine these types into one family, but I can't seem to do this because none of our View Titles actually use parameters so there's nothing to export to a txt file so that I import them into all into same family. Is there a way to merge these types into one family when I only have labels attached, rather than parameters?

Thanks.
