Work-Flow Package

Any ideas - I'm looking for a process management or work-flow package to integrate with my shiny applications. Rather than building out UI components in Shiny, I'm curious if anyone has integrated any packages which help the user track progress through work-flow steps and allow them to return to the application at the last state, i.e. the user left off on work-flow "C" step 4 of 9. Thank you.

I tried to do the same things here : (modalDialog in my shiny app - Dashboard) but it's not easy for me.
if you have some advice, I'll take it!
