Finite Dropdrown values?

Hello


I'm was wondering, if it's possible to make a list of dropdown values available.

But every time one value is used, it's removed from the list of possible options for the following row.


Number 1, 2, 3, 4, 5...

If I then use number 1, it is not possible to select 1 for the next row.

If I then use the number 4, it is not possible for the next row to use 1+4 etc.


I really hope this is possible - thanks in advance!
