You can prevent one or more accounts from being uploaded by using the Do Not Upload List.
...
Once an account is excluded, all uploads for that account will be excluded: executions, adjustments, locates, positions (for reconciliation) and buying power entries (if enabled). 
Note: Data Data that has already been loaded is will not be affected.
Tip: To exclude multiple accounts, you can specify a pattern in the Expression box. Here are some examples:
| Expression | Will Exclude |
|---|---|
| ABC.* | All accounts that start with ABC |
| (?!^ABC).* | All accounts that do not start with ABC |
| (?!^ABC)(?!^XYZ).* | All accounts that do not start with ABC or XYZ |
| ^[0-9]+$ | All numeric accounts |
| ^.*CAD$ | All accounts ending in CAD |
| ABC[0-9][0-9][0-9] | All acounts starting with ABC followed by three digits |
The pattern syntax used patterns used are Perl Compatible Regular Expressions. Their syntax is described in detail here.
