How to create and assign Multiple tasks in a workflow for approval

Guys i am trying to create a workflow for plantfloor Applications approval, basically a user requests multiple applications and for each application we have 3 leves of approvals. so i want help in creating a dialog worklfow with multiple  tasks for each of level1 manger based on the selected user applications.

Example:

User selceted apps:

App1 m1(Manager1), m2, m3

App2 m1, m2, m3

App3 m1, m2, m3

so there will be 3 dialog workflow for approvals with

all m1Array in the first dialog workflow

all m2Array in the second dialog worklfow

all m3Array in the third dialog worklfow.

So what i need is, Is there a way to create multiple tasks for the each manager Array in a single dialog workflow.
