How do I filter by order of activity?

[Anonymous]

Hi, 

I'm trying to figure out how to create a Smart List or report based on the order of activities...so, for example, I'd like to see a list of everyone who filled out a form to download a white paper first and later on attended a webinar. I know I can look at activity by time span, but I don't know how to look at it by relative order to other activities. 

Any thoughts on how I could do this?

No easy way to do this.
