[moneydance] VAT/GST support per installation, per file, per account?

[Cortjan Koppen]

The solution of my 'problem' may stare me in the face, but if it does  
I need some help to get it to my brain.

I have one installation of Moneydance on my Mac. There currently are  
two files which I defined, one handling my personal finances and one  
handling family finances. Each file contains several accounts, in most  
cases I started one account per bank (there are e.g. several saving  
accounts per file).
I deactivated VAT support in the General Preferences.

Now I want to start using MD for my company too. A new file can  
contain all necessary business accounts. Therefore I need VAT support.  
If VAT support is activated, ALL files in MD will show the VAT-stuff,  
i.e. my company accounts AND my two private financial environments  
(files).

Question: is there a possibility to use VAT only in one environment  
(in one file, containing several accounts)?

Thanks for any ideas.

Cortjan.
