"default" Business in "Businesses" tab listing?

I have several older “businesses”, which I don’t necessarily want to remove, listed in the initial Businesses tab, and one of them has an initial of, I believe, the account holder’s name to the left, presumably on the default business, which it actually is not.

Is there some way to set the default business that Manager will open? For now I’ve just labelled it as “USE THIS!”

This is the desktop version.

If you rename the business with a 1 in front of it, it will appear at the top of the listings.
In the desktop version I’m using the ‘rename’ is at the top left of the Summary screen.

This only renames the file, not the actual business details.

Well, gosh, that works just fine, so thank you very much!!
