The former Preston striker received the call into action after regular starter Robbie Fowler was injured in training and is now hoping to be handed his first start at COMS on Saturday.
"It was great to get a first team ninety minutes and a goal under my belt and now I will have to wait and see what happens at the weekend," Macken told the official club website.
"It was hard work but that was always going to be the case after not playing much recently."
The Blues are now looking forward to a home tie in the fourth round against Spurs on 25 January.
Macken said: "It would be nice to think we could go on a really good cup run now and give the fans something to get excited about but we also need league points starting on Saturday against Blackburn."
The 26-year-old added: "Who knows what that win might kick-start. We badly needed that victory to get people off our backs.
"We have not played well at times but we haven't deserved fourteen games without a win. Now it would be nice to go fourteen without losing."
