How do I slow down the troops deployment in v5.5.1.1?

how do you do this for 5.1.1? i really wanna see ( for at least once ) how it looks like when it deploys everytroop at once LOL

So i can't do nothing to change the spawn time of each soldier (not between each wave), i would like to deploy the first soldier than the second after 1sec(or less) the third after 1sec(or less) etc...
