If I want to change x-values in a multi-series X-Y scatter

I have to edit x-values seperately for each series

e.g i have 7 series - i have to edit all 7 x-values (even though the new
x-values are the same for all series)

i must've missed something - isn't there a way to set the same x-values for
all series at once

no-coding solutions - thanx
