Reply to Effect Build Up?

Hey Guys,
I registered in this community today, because i saw a lot of djtt-videos and i hope you all can help me with my problem.

I use a Traktor S4 with Traktor Pro and i use 2 Effects, the Reverb T3 and the Delay T3 for all Decks together.
I love to make buildups with delays and reverbs to kick in the beat after a break.
My problem is that when I cut out the lows, with a filter or the eq and rise up the effect, theres time left to press the refresh button of the effect but i often not have enough time to bring the lows in.
Does anyone know how I could better do that or how i could map something to do this better?

Sorry for my bad english, i'm from germany.
