Hi Chuck,
Thank you for your input! I will add your vote to a similar idea in our backlog (which awaits for further consideration; no particular plans to implement this yet).
Currently, import options regarding import frequency are quite simple, though, you may want to consider using/combining currently available options. Check out another community thread regarding that: https://community.eazybi.com/t/cron-expression-for-import
