Continue counting through multiple Sheets Excel 2016

Hey everyone,

I looked everywhere for a solution to my problem but couldn't find one.

So my situation is like this, I use one Excel file for every worker in our company (for working hours) and every worker has his/her own sheet of course.
Every sheet is numbered in a cell in the table, the sheets are in alphabetical order. My problem is when we have a new employee, s/he gets a new sheet and the sheet must be numbered.

Is it possible to make a reference sheet with a reference cell at the very beginning with a 0 maybe and that every other sheet keeps counting up?
Thank you all in advance!

Do you mean you want the new sheets to autonumber one way or another?

In a way, yes. Is it possible or am I asking for too much?
