I haven't flown on M&M carriers for a few months but on many other carriers this is fine. Some carriers will let you put the FF number that you have status on in the FQTS field and the one which you wish to credit points to in the FQTV field - but if you do this, it is worth checking that the numbers are in there the right way round.
An alternative is to book with one number and change the number after entering or on exiting the lounge or at the gate. Like the FQTS/FQTV method, this does have some risks, as you are may not always to get a new BP back specifying the programme you are crediting to.
Either method should make receiving additional baggage allowances and priority security/preferred seating (where offered) easier, compared to just showing a *A status card, as the status should be reflected on the BP.
