VPP Skill Question

[mobulis]

When I first created my char with a VPP I did not buy a skill to change it, now that I've played him a bit

I want to change that, can I designate one of the skills I already have as the skill to change or do I have to buy a brand new skill?

 

 

 

EDIT:Lets say that I bought the disguise skill for this, then later I spend exp to buy requires no skill roll, would I be able to use the skill for disguise?

The rules state that you have to buy a specific form of the Power Skill to change a VPP. You can't just use some existing Skill. However, as always, what the GM's willing to permit is up to him.
