AFC Telford’s last-gasp victory at Solihull Moors catapulted the club in the semi-finals.
They are now two games away from Wembley and the excitement is growing.
Daniel Udoh snatched a very late winner to book the Bucks’ last four place and Cowan hopes lightening can strike twice.
“I think the victory was fully justified,” he said.
“It was a phenomenal feelings to come to a club right at the top of the National League and win.
“We have loved the ride in the FA Trophy this season - the supporters have too, you can see that.
“I can’t speak highly enough of the players and of course the fans. There’s no better way to win a game than in the last few minutes like that.
“Now we are just one round from Wembley. But we don’t want it to stop - we want to see if we can reach a final.
“Brackley did it from our league last year and maybe another National League North club can again.”
