Hello Daxcious,
As far as avoiding that screen for how long to activate the focus, you can set up a Focus schedule. Use Focus on Apple Watch - Apple Support.
Create a Focus schedule
On Apple Watch you can schedule when each Focus occurs—you can even choose to have a Focus start at different times of the day. For example, you could schedule the Work Focus to start at 9 AM and end at noon, Monday through Friday. From noon to 1 PM you may have no Focus or have a Personal Focus take over. Then, start the Work Focus again from 1 PM until 5 PM, Monday through Thursday.
1. Open the Settings app
on your Apple Watch.
2. Tap Focus, tap a Focus—Work, for example—then tap “Add new.”
3. Tap the From and To fields and enter the times you want the Focus to begin and end.
4. Scroll down, then choose days when the Focus will be active.
5. Tap < in the top-left corner to save the Focus.
6. Repeat this process to add other events to the Focus.
Other than that, you can request these changes be made to the iOS overall at Apple's Product Feedback - Apple page.
We hope this information helps you out.
Cheers!
