first of all I'm a new Customer of iCompta and i am very happy with this software

The only problem that i am having is the following.
I have created several accounts in iCompta. At the right side at the bottom is shown the "All Account" with the sum of all of my account. What i want to do is to exclude one or two accounts from this "calculation". Is this possible? If not, it will be nice to include it as feature in the next update.
What i really mean is shown in the example beneath.
Exp:
1. Account Home - 100 €
2. Account Study - 300 € -( i want this account not to calculated at the "All Account" Sum. Exclude it from calculation)
3. Account Work - 200 €
ALL ACCOUNT - 600 € !!! (i want here to exclude the Study Account and show me 300 € (Work + Home) and not 600 €)
I hoppe You understand what i mean

Thanks a lot in advance.
Regards
Romeo
