need help with a macro to make certain text within the entire sheet BOLD

Hello Everybody
I'm looking for a way to take my pivot table created from a list of values
and to make certain items in the pivot table Bold with a Macro

the list changes Daily, and the placement of items changes with it

so it needs to be flexible as to size in rows to allow for more or less rows in the pivot table each day

I do not mind having to have another sheet with a predefined list on it if that is what it takes

but for example, in my sheet - in the "pivot outbound" tab
I have a couple of items Manually set to Bold
and I'd like to be able to run a Macro to do this task for me

it needs to be for every instance of those values in the entire sheet, not just cell "F6" every time

Thanks for your help
it will be greatly appreciated
