can we have two subscreens in a single tabstrip

Hi All,

Can we have two subscreens in a single tabstrip based on some condition.

for ex:

if matchar = 'E'.

I need to call subscreen 9001.

or if marchr = 'S'.

I need to call subscren 9002.

Is that possible to do that. if it is there, please let me know..

Thanks
