Combine multiple choice answers with repeat

Question

I am developing a survey123 form regarding transportation. I want to find out how long the person was travelling by which means. I thought of using a multiple choice field first with means of transport (walk, bus, taxi, bike) and then a repeat which autofills automatically the chosen means of transport (_1, _2,_3...) from the question before and a integer field to give the minutes per means of transport. Is there a way to accomplish this?

Let me give you an example.

Question 1: Did you use other means of transport before going on this bus?

Select_multiple Answer(s): Bus, walking

Repeat (if Answer to 1 is not empty):

Question 2a : Means of transport

Answer 2a (auto-populated from Q1): Bus

Question 2b: How much time did you spend?

Answer (integer)(in minutes): 20

end Repeat

I would like to set the number of repeats automatically to the number of selected answers in Q1. And Answer 2a should automatically populate from the answers of Q1.

From the strategy I guess I would need to find out first if there were more than one answer selected in Q1 (which could be solved by looking for comma -> true/false). If true I guess I would need something to split up the string in Q1 at the comma and use the results separately in 2a. If false I could just use the answer from Q1 as default for 2a (plus readonly).

Did it become a bit clearer now?

not following then.... I thought you had a base question with multiple choice answers, then you would repeat it and alter the correct choice answer as needed.  That would save you repeating the answer text multiple times.

If that isn't it, maybe an example

Well, I know how to do multiple choice questions and also repeats. But the question is: how do I get the answers of my multiple choice question separated and then populated in my repeat answer?
