Variable time gap in Session Window

[Teena Kappen // BPRISE]

Hi,

Is it possible to have a variable value inside the time field for session 
window?

input
    .keyBy(<key selector>)
    .window(ProcessingTimeSessionWindows.withGap(Time.minutes(10)))
    .<windowed transformation>(<window function>);
In the above code, instead of the value 10, which will be the same for all 
records, is it possible to have a value which can be picked from the record 
that comes in?

Regards,
Teena
