Howto change call type without losing parameters

Hi all,

I'm having a problem with almost all my sequence files. I need to change the labview call type from a "VI call" to "Class Member Call". And I need to do this for all my labview steps. 

But when I change it by selecting the right call type, then I lose all my parameters for the vi.

Is there a way to convert all call type to a specific call type without losing parameters?

I'm using TestStand 2016 SP1 b.t.w.

Many thanks,

Erik
