Adding logic for a question that has multiple options to select and each option has further ans

I just found out that i can only add limited options to a logic-based question (s) on the form

So I have a question that has 8 options for a user to select from and these 8 options expand to 4 each sub-options for them. Now while building this on the form, I am stuck how can I expand these. What I was doing adding logic for each question but it can only go as far as for 4 options. What is the most efficient way to solve this. For example; if the question is: Select the day you will come to office? (My options are: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday, Prefer Remote) Then each of the options has (Morning, noon, evening, night) how can i create this question on the form? I want the sub-options to appear only when a certain value is selected.
