Using PeopleSoft User Lists for Custom process

Hello,

Is it feasible to use User Lists which are of the type Class, to trigger emails using an application engine process?

I have a requirement where an application engine process would need to send emails to the manager of the employees. I already have a custom page wherein I can specify a User List. I want the application engine to pick the User List specified at that page, resolve it to find the appropriate users and then trigger the email to them. This would prevent hard-coding and enable us to change the recipients of the email as desired.

I plan to specify and use the delivered User List "By Partial Pos Mgmt - Suprvsor" for this.
