Hey KS Welcome to the forums. Are you new to the program? If so please check out some of my videos on you tube if you want.
To do what you are asking is pretty simple. Make sure all your fixtures are linked to the Master Page by going to the pages tab and making sure the crown icon is on for each fixture page. now once you have done that go to the master page and click on the INIT scene to make the page active. Now select new scene but clicking on the yellow "SCE" icon or go to button at the top and select New Scene.
A window will pop out that says master scene 1. you can rename it to whatever you wish. now towards the bottom of that pop up you will see a check box that says link all the channels of the page to easy step. check it. and then select OK+EDIT.
Now in the scene edit window you position your fixtures how you want too using the faders. to move all of the relevant faders for one fixture type hold down shift as you move the fader for example say the pan or tilt or dimmer channel. All like channels will move to the same level as the current one being adjusted. Once you have your first step as you described in your post you can create a new step in the same scene using easy step.
to make a new step click on the square gray box that has a page in it with a arrow pointing back. now you can adjust your fixtures for your next step and add a fade or hold time in the boxes with )'s in them. The upper box is for fades the lower box is for hold.
I hope this helps you. if i skipped anything or you have further questions please let me know.
