How to add another sum onto a Metric

[Lamda]

Hey All,

So I have a table with some simple fields - the ones I want to focus on is Store, Fruit, and a metric Employee Count. The purpose of the report i'm trying to put together is to show how many employee's at a given store sold which fruit. Obviously I have simplified this a good deal, lol. But a simple return for store 1 would be:

Store Fruit Employee_Count
1 Apples 10
Banana 5
Oranges 3
Pears 2

So the way to read this for Store 1 would be that 10 employee's sold Apples, 5 sold Banana's, etc. Now the higher-ups would like to add a metric to show underneath this for How many employee's have sold one of each of the fruits. So that would look like:

Store Fruit Employee_Count
1 Apples 10
Banana 5
Oranges 3
Pears 2
All Fruit 1

So this reads the same as above with the addition of 1 Employee sold all 4 fruits.

My issue is that I am at a loss at how to add this separate metric onto an existing metric. I think it would be a dax formula as an addition to the above Employee_Count metric that would some how count when an employee has a count of all but i'm unsure how to do it. Any suggestions would be greatly appreciated!!!
