Hi,
I would advise looking at a permanent solution that won't need an interaction to ""allow macro"" however, to give you a quick answer regarding the wait stage, you can leave parameters blank which will give you a basic sleep period.
For build efficiency & design:
-If you are in a Business Object, use the Wait Stages depicted by duel stop watches
-If you are in a Process, use the ""Sleep"" action within General Utilities
Let me know if I can help with anything else.
Thanks,
James
