SecuritySuite - SuiteCRM and CE Teams

This is actually three questions. I am using the trial version of Security Suite version 6.5.18 installed in SuiteCRM version 7.1.4. Question 1: We have four different user assignments (sales rep, secondary sales rep, applications engineer and aftermarket rep) that we might want to make on each opportunity and the users assigned to these duties will be different for each opportunity--dynamic teams. I was thinking that Security Suite would allow me to assign a single opportunity to these 4 individuals and then they would all see the opportunity in My Opportunities. But now I am thinking that Security Suite will only handle static teams. Is this true? Question 2: We would like to have access to the login as any user functionality but I don't see it anywhere. I read the documentation and it appeared that I would see a new action on the User Detail view to login as that user. My customer definitely wants this but I need to test it out to make sure has the desired functionality.Question 3: I was already using Security Groups in SuiteCRM. Does Security Suite version 6.5.18 give me any additional capabilities? Thanks, Dianna Whitt
