More complex target group selection in mailing.

Is it possible to have a more complex target group selection when sending a mailing?

For example, a mailing with the following requirements:
* Recipient MUST be in one of target groups A, B, C
* Recipient also MUST be in one of target groups 1, 2, 3, 4

I know that OpenEMM allows me to select these target groups such that a recipient can be in any one of those groups (A | B | C | 1 | 2 | 3 | 4), or the recipient must be in all seven of the groups (A & B & C & 1 & 2 & 3 & 4), but can it be set to the requirements that I outlined above? I tried setting mailing_tbl.target_expression = '(A | B | C) & (1 | 2 | 3 | 4)' but that doesn't seem to accomplish anything.
