Using Event Framework and SavePreChange is it possible to prompt a user for change comments?

I'd like to use the Event Framework to attach an application package to a configuration component so that I can prompt a user for comments when they make and save those changes.

When reviewing the Prompt command I find that it is a "Think Time" command and cannot be injected during SavePreChange

I've been reviewing DoModalXComponent thinking that I might be able to throw up a modal page prompting the user for comments but it requires a common work record shared between my comments component and any target component making this unfeasible.

I'm hoping maybe some of you might have other ideas that I might not have considered.
