You can “tune in” before bed, not just in the morning. Morning routines are good, but sometimes life gets in the way. You can always do the meditations laying down (in bed!), or for a shorter amount of time. But you make effort to show up for yourself, and strengthen your trust muscle with yourself. And, if the day ends and you remember that you forgot to do your meditation, that's still great! Otherwise, the subconscious is burying it so you don't even remember.
Don't be so neurotic that you hold onto an "ideal" schedule that doesn't work for you. 24 hours is a lot of time, and shouldn’t be the same for everyone. Utilize your day. For example, we all need different amounts of sleep. Take naps. If you have command of your endocrine system, then anytime you sleep, you can command your body to rejuvenate and replenish itself. Sadhana can happen as early as 2:30 AM. You put together your day as it works for you and your household.
Most people have a mix of four things that work the best for them: sleep, food, exercise, and meditation. If you're feeling off, you need more of these or to rebalance them.
