Modals on top of modals 2 answers

The product I am working on at the moment is a standalone product but we are creating a web app to replace it.

It currently opens modal windows on top of modal windows for the same function

i.e Create new report (modal) > add person to report (modal)

Is there a known best practice for making this nicer to use without using a wizard?
