Time range grouping

Just wondering if this is possible. I’d like to have a smart list that groups tasks from 5-6 different reminders lists by morning/afternoon/evening. I have 3 smart lists that filter based on:
Date=today
Time=[range]
…so that the three lists each pull in tasks dated today for their corresponding chunk of the day. I’d like to be able to view all 3 as in a smart list, but as far as I can tell you can’t make a smart list of other smart lists. Is there a way to view all 3 of these at once in a list or board view? Or maybe another way to approach getting the perspective I’m going for via a single list? The only way I can think of is to use tags and manually adjust whenever I adjust the time of a reminder but it would be nice to not have the additional synchronization step in there.

Hi @Matt_Hendrickson, thanks for the feedback.

Unfortunately it can't be done on current status. I'll keep your feedback on the list to consider. Thanks!
