Project Scheduling on Actual dates of Activity

Dear All,

Can we schedule a Project after actual Confirmation of Internal Activity.

Scenario: I have a project with start date 01.01.2014 and end date 31.12.2016. with some Activities with Relationship and Scheduled.

                      Basic Start Date        Basic Finish date      Actual Start Date           Actual Finish Date

Activity 1          01.01.2014               15.01.2014               01.01.2014                    15.01.2014

Activity 2          10.01.2014               20.01.2014               10.01.2015                    20.01.2015

due to some reason there are a Delay of 1 year in the Schedule. Now  i want that further Activities be scheduled According to the Actual Start Date of Second Activity. is is possible in Standard system. or what is the Procedure to adopt this.

Thanks
