Clear Data Depending On User Input And Move Cells Forward Without Deleting Data Table

I have an month input in cells B2 (user can enter values from 1-5)

I then have a data table that has month 1,2,3,4,5 running across range G9:K9. the data is held in range G10:K19.

So if user types in 4 in B2, what should happen is that months 1,2,3 and 4 the data for these months should be cleared and data in month 5 moves forward into month 1.

So basically, anything left of the month entered is B2 should be cleared and replaced with anything right of the month in B2.
