Alert Reminder Time frame not realistic -- Custom time frame feature request

As you can see in the image below the only times for a reminder are 10 mins, 1 hour, 3 hours, Tomorrow, and Next Week.

I don’t make robot calls all day so these short time frames aren’t realistic. What about being able to specify a date. Add a calendar with time of day etc. Some customers tell us specific times so the work around is to either choose next week every week and waste time doing that. Or double dip and make a reminder in Outlook or using another calendar. Doubling efforts here too. Hope this request makes sense. It’s not complicated.
