VBA To Capture Info Using Filter On Specific Column

I'm trying to add code to an existing macro that is working well to add a feature.

As it sits now, my code produces a worksheet tab called "Matrix" that has headers in row 1, a variable length list of employee names in column 1, and then a variable number columns with data crossreferenced by name in the body of the spreadsheet. Not every row/column intersection has data, some are blank if the ItemXname does not apply to that individual.

What I want to do is select all the cells on this spreadsheet, apply a filter, and then filter based on the selection of names in column 1. But I want to do this using VBA, where the macro runs, it asks the user if they want to filter on one or more names. If no, then it skips this part. But if yes, then the next thing they see is the filter window like they would see if you did this manually. After making their selections and hitting ok, the VBA routine would then take their selections (some finite number, but could be 5 -10 names) and process the rest of the macro accordingly.
