[GNC] Keeping two sets of books

[taf]

Hello,

I've just started using Gnucash.  In the past I've used a basic 
bookkeeping package, but it's no longer available. I'm trying to keep 
two sets of books... one for personal accounting and one for a 
corporation.  I'm running Version 3.4 Build ID: 3.4+ (2018-12-30) on 
Windows 7; I've set up the books, saving the books into two different 
MySql data bases with separate users and passwords.  So far so good. I 
can switch between sets of books by selecting

File->Open...->

and then in the Open dialog, selecting MySql data format and specifying 
database, userid, and password.  This seems to be a bit klunky... am I 
missing something fundamental?

Ideally I'd like to have two desktop shortcuts, one to use each set of 
books, specifying at least format, database and user within the shortcut.

So... any help?
