MarketFeeder remember - is it always global?

I am using the remember command as below
With this I can get the value of top_1_sel_index
The problem is the the 'top' variable seems to be global.  I want it to be local to the event.  I tried initialising a variable called top as 'individually for each event' with a value of zero but this didn't help.  This is a problem when multiple events are happening at the same time.
Maybe there's an easier way of knowing the index of any selections that have bets eg that have layed on Betfair web site outside of the trigger?

Hi
Add event_id to the remember name: top_event_id
then to address the value: top_event_id_1_sel_index
