Psionic Powers help

[SAbel]

So a lot of psionic powers have a power that needs to be activated (and maintained) that then allow the character to have an attack power (see below ex. Living Missile). How do I make the powers so that when the player picks the main power it generates the attack power and makes a card for it?



Example:
Level 1 Living Missile
Psion Attack
You bind an enemy with a thought, then hurl it into another foe.
Daily Implement, Psionic
Standard Action Ranged 10
Primary Target: One creature
Primary Attack: Intelligence vs. Fortitude
Hit: The target is immobilized (save ends).
Miss: The target is slowed (save ends).
Effect: While the target is immobilized or slowed by this power, you can use the Living Missile Attack power once per round.

Living Missile Attack
Daily Implement, Psionic
Minor Action Ranged 10
Requirement: The power Living Missile must be active in order to use this power. This power may be used once per round.
Effect: Before the secondary attack, you slide the primary target 10 squares.
Secondary Target: One creature adjacent to the primary target at any point during the slide
Secondary Attack: Intelligence vs. Reflex
Hit: 2d6 + Intelligence modifier damage, and the secondary target falls prone. The primary target takes half damage and falls prone.
Miss: Half damage, and the primary target falls prone.
