Hi guys, I'll make it real quick.

I want to add a 4 days interval between dates after 4 consecutive days (regardless weekends), similar to roster/shift ie:
A1 to D1 = 1-Jan, 2-Jan, 3-Jan, 4-Jan
E1 to H1 = 9-Jan, 10-Jan, 11-Jan, 12-Jan
I1 to L1 = 16-Jan and so on....

Is there an Einstein way how to formulate this format? Thanks heaps guys.
