How to add a constraint when matching using teffects psmatch, cem or psmatch2?

Hello dear statalists,
I am trying to match the houses sold at year t with similar houses sold in year t-1, t-2,..., t-5, respectively. That means apart from controlling for housing characteristic, I also need to add a constraint on trade_year. How can I do that with teffects psmatch, cem, psmatch2, or other Stata commands?
