Need help creating a custom SP list

Hello,

I have 15 employees that need to respond if they have documents related to a group of 10 current assignments.  These assignments are located on our intranet.  We want those responses to be "Yes", "No", or "Pending."   This allows me to see how many employees have assignment related materials.  A new assignment comes in each week to which the same 15 employees need to respond the same way.  

We currently have the employees respond to an Outlook email via the voting feature, which sends 15 emails to the originator of the email which gets very messy and is impossible to track or run data from.

We'd like to migrate this process to SharePoint.  I envision some sort of list that has these 10 assignments, with a space for each of the employees to respond "Yes, No, or Pending."  I was thinking each assignment could be a collapsible section, and when the section expands it could open a table.  The rows could be the employees, so perhaps 15 rows, with a couple columns for the responses.  Thus, 10 single line collapsible sections in a sort of bullet-point setup.

Is this possible in SharePoint? Or does anyone have a better idea on how to do this?  Currently I don't know how to add in the collapse feature.  I really don't want to have to make a document library and have a list for each assignment.

My only other thought is to make each assignment a simple text webpart and then add in lists of employees underneath each one.

Thanks.
