Best way to combine the exercises from a program?

To put it shortly, i am wondering if there is any information on which exercises to do each day from a particular program? Example: “The desk posture fix” program has 20 exercises(videos) which i can’t do all in one day. So if i want to do 5-6 exercises a day from that program is there any suggestion on which exercises to combine, thinking if there are 1-2(or more) exercises that are core exercises and should be done each day and some exercises to be of less importance and can be combined in any way. I am taking inspiration for this post from the previous app, where there were “phases”(2 weeks intervals) in each program where exercises(4-5 a day) were combined differently in each phase(a few exercises were always present in each phase so i assumed those were important/core)
