No that's not supported, but don't forget that you can always use non-marking parenthesis to avoid throwing out too many fields.

I already use non-marking parenthesis but when using a long regex it's very difficult to decide which is the correct index to define the subexpression to use. Furthermore, when using "conditional expressiones" in the format strings the difficulties are even more obvious... Thanks anyway for your reply, Jordi
