Run an automation based off a primary automation?

I have been tasked to create an automation for alerting someone about entering in Smartsheet details the day after the primary automation sends them an initial request to input their information. My question is, is this even possible? I've been doing some experimentation and it does not seem that I am able to create an automation to send a follow up alert or update if the individual forgets to input their info the first time around. Any ideas on how to do this otherwise? Thanks! The context is travelling dates and airfare costs.
