Excel – linking cells between 2 sheets

I have 2 sheets, sheet 1 look like this:
Col A Col. B
H due date
G
V
T
H due date
G
V
Sheet 2 has dates
row 1: 010207
row 2: 020307
I would like sheet 2 date data populated to sheet 1 where the cell says due date automatically when data paste to sheet2. Data size for sheet 2 will be 2K lines.

Any good idea w/o link cell by cell for a template? Thank you!
