Create sliders depending on answers from matrix question

I have a matrix question where respondents can select one or more time slots for each day of the week. The matrix is supposed to look like a calendar with days (columns) and time slots (rows). 
Then, in the next question, I want to ask respondents to indicate a percentage on a slider for the selected time slots. I am trying to create separate slider questions for each selected time point in the matrix question, with the appropriate time and day of the week displayed in the slider label. 
I tried to use the carry forward function to carry the selected time slots from the matrix to the slider labels. Also I integrated a loop that loops through the days of the matrix. This does not really work, as it loops through the days but presents every selected time slot of the whole matrix for every day not just the ones selected for the specific days (see below).
Is there another way to create these slider questions dynamically depending on the selected time slots from the matrix question?
