Track 2 / Track 4 / Member selection

Hello,

I would like answer you about the command MEMBER SELECTION using Track 2 (stress)  and Track 4 (serviceability) commands for Eurocode

I know make a perform analysis checking serviceabily and stress like this

LOAD LIST -----

PARAMETER 1  // This is for serviceability check or deflection check

TRACK 4 ALL

**********

CHECK CODE All

LOAD LIST -----

PARAMETER 2 // This is for stress check using ultimate load cases

TRACK 2 ALL

************

CHECK CODE ALL

I know use member selection / group option like this

LOAD LIST -----

PARAMETER 1 

// parameter list

Ly 

Lz

py

ratio

TRACK 2

......

Perform analysis    // first analysys

    Select member ----

    Group member ---

Perform analysis    // second analysys

     Select member ----

     Group member ---

Code check all

And my questions is how can I use MEMBER SELECTION checking serviceabily (track 4) and stress (track 4) toghether??
