Go to a cell in column, based on a reference number

I've attached a spreadhseet utlizing the formula that was provided by Trebor76. I've set up this spreadhseet so that if I enter an "x" or any other character in Column E under RFA then it will do a timestamp in the column next to it. What I want to do now is be able to enter a value in cell A1 go to the cell 4 columns over (it already does this) but additionally i want it to enter an "x" and then return to cell A1.

Is this possible??
