Forms :: Combo Box - Can Auto Dropdown To A Specific Row From Hidden ID

I have a combo box that I normally type the start of a Surname and it auto drops down from underlying database ID is now show in col count, only 1st two.

Surname Name ID
jones/k kelly 33333
smith/m max 12345
smith/m monty 98765
white/t tom 55555

smith/m will short list to the two above, I can mouse click or arrow down to the 2nd one Press enter & its knowa the corresponding ID (= surname.Column(2)) and goes to the correct record.

What I am trying to do, is from another part of my program, eg an incoming email with the corresponding Surname, Name & ID Automatically go to this main booking form, auto enter surname "smith/m" - which is fine, the list shortens but It goes to the first matching on the list, ie max.

Is there a way to get it to go to monty using the ID 98765 which is unique.

Perhaps an odd request but actually nice to book each time through this same main form, I actually also want it to do the same from incoming phone calls, It can get the unique ID ok but can see a way for the combo box to jump to the correct & only row from underlying register.

Bit worried about trying to change the underlying select statement that the combo seems to be based on, perhaps this is the way forward but not sure how to do this & don;t want to risk messing the most important & already functioning well normal entry style.
