Multiple Combo Box Reference List But Remove Used Values

i have a list of 5 teams in a named range ("teams") within a worksheet.

On a userform I have 5 combo boxes.

What I would like to have is an easy way to remove a used name in the list for the next combo box.

i.e. someone selects team a in combobox1, combobox2 then has a list of team b,c,d and e. I'll be locking the combo boxes and writing code so the next one will unlock if the previous box is populated.

i also need this to work if someone puts team c in first combobox this then gets removed in combobox2 then in combobox2 they input team e then both these values are removed for combobox3.

only way I can think of doing it is creating a lot of named ranges and using a lot of if then code which I'd like to avoid.
