I am not sure if the following is possible, but if anyone knows, I
would greatly appreciate some help here.
What I have is the below columns of data (in A through C) (data of
course has been changed)

A B C
12345 zt12345a PizzaHutLarge
12345 xr12345a PizzaHutSmall
56789 ab56789b DominosLarge
56789 df56789a DominosSmall
23567 ty23567h PapaJohnLarge
23567 rp23567q PapaJohnSmall
23567 qw23567a PapaJohnMedium

These columns go down a couple thousand rows of data. What I would
like to allow the user to do is copy and paste unique values found in
column A into another cell column (in D let's say) and then in column
E it would list all the values from B associated with it.

For example, if the user pasted 12345 & 23567 in column D, then in
column E, the result would be

zt12345a
xr12345a
ty23567h
rp23567q
qw23567a


Can this be done? Any help is greatly appreciated.

Thanks in advance.

ps - I have a workaround for this situation, but I wanted to see if
the above was possible.
