Hello,
I am trying to rename a specific cell in my semi-unformatted dataset:

I want to edit the 4 Placeholder values in this data. The way I currently have it setup is to use 4 Find/Replace tools:

Using a Rename Grid like this: -

And then output the file with the renamed values
Had two questions from this:
1. Is there a way I can have Alteryx target a specific cell (e.g. change Cell B4 "Placeholder1" --> "Blue" -- instead of the Find replace tool that looks at column F2 / F6
This would avoid the case where there are multiple "Placeholder1" values in column F2. I only want Alteryx to change cell Placeholder1 in cell B4.
2. Is there a way to iterate this workflow, so if I add a second row to my Rename grid -- two output files will be produced, with the two different sets of renamed Placeholder values? Want to eventually add 6 entries in my Rename grid

Workflow and input dataset attached.
Thank you!
