Post to Google Classrom one time per week

I would like students to have the full week on one page. If I were to use the Google Card as it works now, I would be back to many assignments for each day and many, many assignments for each week. So, for now, It is an incredibly handy tool for the "traditional" way Google Classroom is used, and its update feature is a winner. But, having all the week's lessons on one post works better for me and my students.
