Export Function multiple times

Dear All,

I am fairly new to JS and just started to explore it.
Currently I am trying to assign a function to elements when they are clicked.
I followed the tutorials on Corvid and it ended up hideously long.

Basically I have 50 buttons assigned to 5 groups.

For each button, there will be a ‘OnClick’ event and pass a relevant value to another function ‘sotreSelection’ and return the readable value to an GTM event as the following

export function gmapAA_click(event) {
 storeSelection(0);
 console.log(`Execute Successful': ${selectedStore}`);
 customEvent(selectedStore,event);
}

Therefore the next export function will be:

export function gmapAB_click(event) {  
 storeSelection(1);  
 console.log(`Execute Successful': ${selectedStore}`);   
 customEvent(selectedStore,event); 
}  

Is there any clearer way to process what I am after?
Thank you.
