How to create multiple new columns or variables conditionally and concatenate multiple variables

[ds21]

I have attached an example of what my SAS data looks like. I want to create a dataset that has a separate column for each day (1,2,3 etc), with times concatenated into a second column. I want the result to look something like this:

ID  Day1      Time                       Day2      Time                      Day3             Time                    Day 4        Time                   
1   Monday  10:00AM-12:00pm Tuesday  9:00AM-4:00PM                                                    Thursday   4:00PM - 9:00PM

2                                                                                             Wednesday    5:00PM-8:00PM Thursday  9:00AM - 1:00PM

3   Monday  8:00AM-12:00pm                                                                                                 Thursday   5:00PM - 12:00AM

So basically I want the dataset so that the first day column only lists all Monday availability, the second day column lists all Tuesday availability, etc. and then to concatenate their start and end times together into one column. That way, it's easy to see everyone's days and times in order of day of week, instead of all together as in the example where it's difficult to determine everyone with a Monday preference. I'm ok with a data step or proc sql.

This seems largely presentational.

Could you post some data in a data step?
