Have an array formula, need to keep part of it and delete rest

[Badnames]

I have a transpose formula, which takes data from 12 months. I now need to only have it pull the last 7 months and I will put values for the first 5 months. I need to delete the first five cells and keep the formula active for the last seven cells. This same formula is used in 55 workbooks, each containing 40 worksheets, 37 of the worksheets has the formula. Is there a way I can quickly fix this in each workbook? I cant copy and paste values because then I have to rewrite the formula in all the cells. The rows are always the same, 619:625. but the letters/columns are anywhere from I:GG.

I tried doing a find replace all on the range of 614:625 to 619:625. Doing this gave me the correct data for the last seven months in the first seven months cells. Is there a way I can move it to just cover the last seven cells?
