Help please? For store pick-up shipping option -- are choices possible???

My client's shop uses the option of in store pickup as a shipping option (no charge for this). She now has 2 locations and would like to create a drop-down menu so that a customer can state which of the 2 locations they prefer in order to pick up their purchase.

I cannot see a way to do this? Is it possible? And if so, how please?

Thanks much!

You could clone Store Pickup storepickup shipping module so that the two can show at the same time ...

Then you can just change the text in the language files for these and the customer can pick one or the other ...

THANK YOU SO MUCH :)
I suppose I should have done a better search before asking.

Your instructions in this thread were absolutely perfect and worked like a charm!

I did clone storepickup.php as opposed to flat.php (which you seem to have recommended further down in that thread. I wonder whether I will encounter problems?

It appears to be working when I select my shipping option, but have not completed a purchase to be certain.
