Convert formula to column formula without losing existing cell data

Hello,

I have a sheet where I'm trying to add a formula as a column formula so that it applies to new rows, the issue is many cells in the column already have data (Date column) that I don't want to lose. The formula is an INDEX/MATCH that is referencing another sheet to obtain a modified Date. I have a trigger to copy a row when the status is changed to obtain the modified date in Sheet 2

Sheet 1 Columns

Work Order Assigned Date Status

Sheet 2 Columns

Work Order Modified Date

The formula I am using is:

=(IFERROR(INDEX({Sheet2 Modified Date}, MATCH([Work Order]@row, {Sheet2 Work Order}, 0)), ""))

I tried an IF function to check to see if the column was blank and received a "Circular Reference" error.

=(IF([Assigned Date]@row = "", (IFERROR(INDEX({Sheet2 Modified Date}, MATCH([Work Order]@row, {Sheet2 Work Order}, 0)), "")), [Assigned Date]@row))

I have a feeling I will need to create a helper column, but that will clutter my already 40 column Sheet 1 and I still don't know how I would get the original Date into the Assigned Date column.

Any ideas are appreciated

Thanks,

Darren
