Try a batch macro! You will need two inputs to feed into the batch macro - one with the data, and one with a summarized list of store numbers that will feed into the upside ? after your macro is inserted into your workflow. In the macro itself, you configure the Control Parameter to be the value that your filter uses, rather than hard-coding the number - see formula configuration below. Then the rest of your workflow would perform the calculations as desired and output the results in a single file (use a Macro output tool if you want to use those results in the rest of your main workflow.)
Hope that helps point you in the right direction? Let us know if further clarification is needed!
I think you should take time to consume her advice and look at how the workflow has been built. This should provide you with an understanding about how it can be translated to your workflow and situation.
Once you have made an attempt then you can perhaps give some follow up questions that we could help you with in order to reach your solution.
