The sides meet at Scotstoun with the Warriors aiming to extend their lead at the top of the RaboDirect Pro12 league but the flying winger admits there will be no time for reflection after Scott Johnson named 18 Glasgow players in his autumn squad.
He said: "We were straight back to work and concentrating on Munster. You can't dwell on Scotland stuff when you have other big responsibilities. This weekend will be another huge challenge but the confidence is there and the fact that so many Warriors have been recognised by Scotland makes you hope the feelgood factor will bleed into the performance against Munster."
Seymour, who won his first two caps during the summer tour of South Africa, added: "The international squad call ups are particularly great news for youngsters like Mark Bennett and Jonny Gray. Younger and younger guys are realising that, if they are good enough, they are old enough, and that they can be rewarded with promotion to the higher level."
Of the Munster challenge, Seymour said: "It is top v second and they will be wanting to set a couple of records straight. Their most recent memory of coming to Scotland was losing to Edinburgh in the Heineken Cup; they will also remember that we beat them last season.
"But we are a team with momentum and we would like to do to them what Edinburgh achieved."
